It seems like Espressif are in the same situation as Pi w/r/t PlatformIO[1]. As an outsider, it sounds like PlatformIO was trying to extract a very large annual payment from RPi and Espressif, and that was after the initial support was added in, and some of the community started adopting it.
It's a weird situation, but I think PlatformIO built up a dominant position by supporting all these platforms and accepting community contributions to do so, then tried extracting value from the manufacturers directly after the fact, blocking further community PRs that would add new board revisions or fix bugs.

One use case is related to the Nintendo Switch, as mentioned in another post.

probe-rs
A debugging toolset and library for debugging embedded ARM and RISC-V targets on a separate host
If I get your question right, you still need some host software (like a rust compiler)! It's not exactly micropython experience.
The bare minimum would be one of the examples [1] compiled with a Rust compiler and then transformed into a .uf2 file with elf2uf2 [2]. You can then just drag and drop the .uf2 file into the "mass storage device" presented by the bootloader. To get the bootloader to mount, you press a button on a Raspberry Pico (or short two outputs if you're using bare RP2040) while plugging it in.
You'll probably want a debug probe [3] driven by probe-rs [4] at some point, it's just much more convenient to flash and debug with it.

In general, read-out protection provides a very limited level of protection that I wouldn't rely on to stop cloning. There's quite a few firms that will extract the firmware from protected microcontrollers for a couple thousand dollars (i.e. https://russiansemiresearch.com/ ) which is a drop in the bucket considering the potential profit from industrialized cloning. Lots of microcontroller series also have exploits that can allow hobbyists with very little funding to bypass read-out protection (here's one for the STM32F0 series for example: https://github.com/racerxdl/stm32f0-pico-dump ).

We've been using the RP2040 in the electronic badges[1] for the RVASec security conference[2] for the past several years, and it's been very nice to write software for. Here's the github repo for this year's badge (there's a software-only badge simulator so you can kind of play around with it even without the hardware, although some of the multi-player things that rely on infrared badge-to-badge communication won't be any fun): https://github.com/HackRVA/badge2024

I do wonder how much of that can be accounted directly to the RP2040. Projects like QMK[0] have been using a technically quite similar codebase for making DIY keyboards for quite a while now.
At first glance I'm not really seeing anything in GP2040 which couldn't have been done with any other somewhat-modern MCU. The RP2040 has undoubtedly been the catalyst leading to GP2040's widespread adoption, but it seems the same could've happened with a Pro Micro instead.

picogus
Emulation of ISA sound cards on Raspberry Pi Pico (GUS, SB/Adlib, MPU-401, Tandy, CMS) with USB mouse/joystick support
Related: retro PC stuff.
https://github.com/polpo/picogus
Emulates all kinds of sound cards, including the Gravis Ultrasound.
https://github.com/FreddyVRetro/ISA-PicoMEM
Emulates a memory extension, but also so much more stuff.

Have a look at the other repositories of user todbot. He has also got a board with sliders, consisting of inversly tapering touch areas that allow to compute the touch position along the axis (same for rotary sliders that use three of these in a circle configuration).

I'm speaking from experience, I built two boards with the rp2040 before I decided to stop using it.
The pin flexibility is nice, I agree with you there. But I spend more time dealing with the flash chip than that saves me.
I don't want more capability. An STM32 M3 has far far more processing throughput than I need for 99.9% of what I do. I want the smaller thing, even if it isn't cheaper. It is sufficient.
I love stm32s because I can write bare metal C without using any of stmicro's libraries at all (except the one header defining the register offsets). Here's an example: https://github.com/jcalvinowens/ledboard/blob/master/firmwar...
The rp2040 is not set up to easily let you do minimalist stuff like that. And after all, why would they go to the trouble? You have 16MB of flash to waste on library code you never call... it's like buying a mack truck to commute to work.
I'll also echo the other comment about the cache: if you actually have megabytes of .text, you're gonna have a bad time.
