Why Prusa is floundering, and how you can avoid their fate
There is _a lot_ wrong with Marlin. It is a complex codebase, full with ancient artefacts, litterred with preprocessor ifdefs every 2-3 lines of code, dynamic includes in the middle of CPP files, etc[1]. It's about as unreadable as C++ code gets--well, I guess it's not template metaprogramming.
Klipper by contrast is a breeze to read through[2].
I am very grateful for Marlin, for all of reprap, and everyone who has contributed to it. But saying there is nothing wrong with it is straight up misguided.

E steps way off.
I think you are mistaken. I can't speak for implementations preceding the Ender 3 V2, so what you're saying may have been true at some point for other machines. However, here you can see Marlin developers confirm that there is an EEPROM on the stock E2V2 board using diagrams from Creality and photographic confirmation. Here is the datasheet for the EEPROM. Here is a thread discussing this Marlin release, and also the then-recent release of official Creality firmware which resolved the same issue. Since the stock firmware is based on Marlin, and at the time Marlin did not support this type of EEPROM, the EEPROM was not usable at launch. Any mainstream firmware (official or third-party) from the last three years will be using the onboard EEPROM unless the user intentionally specified otherwise.

Anycubic Kobra Marlin 2.1+ based custom firmware
i spent some time and successfully rebased Kobra 2.8.2 OG firmware from an unknown Marlin ~2.0.8 frankenstein to a clean latest (as of now) release (not bugfix) 2.1.x -- v2.1.2.1 + 1 commit

Digraphs and Trigraphs
As an example, check the macropocalypse in Marlin - but the actual trigger for me to start was Reprap firmware doing a floating point divide in interrupt context while targeting AVR8 core…

Need advice on intermittent thermal runaway (Ender 3 V2)
Any change of thermistor or to a PT100/PT1000 will require recompiling the firmware, because every type has different characteristics. Marlin uses an internal table to calculate the temperature for whatever reading it gets from the CPU's analogue-to-digital converter. It has many tables for different thermistors, but only one is ever incorporated at compile time. So you have to specify which type you're using. You can see the commonly-used types in the list in Marlin's Configuration.h file, in the section headed // @section temperature. The tables themselves are in Marlin/src/module/thermistor.

Has anyone actually edited Marlin source code and added a new feature?
FWIW It IS open source but the GNU General Public License v3.0 rules apply. https://github.com/MarlinFirmware/Marlin/blob/bugfix-2.1.x/LICENSE

Creality Print vs Cura: Speed
So I'm using beta version of Cura (5.5.0) with V3 SE profile from https://github.com/Ultimaker/Cura/pull/16796 and I just figured out that Creality print is way faster than Cura. As far as I can see, settings are almost identical; print speed is set to 180mm/s in both programs. I'm using stock PLA profile in Creality print and eSun pla+ profile in Cura - same temperature, infill, walls and fan settings.

New Feature for Cura?
In this case, Cura is an open source project, so the most straightforward way of submitting a feature request would be by creating an Issue in the code repository, where you can explain your idea along with why it’s important to you, who else you think it could be valuable to, and what you want both minimally and ideally.

Updated to Cura 5.4 and it wiped everything, now I cannot select Ender 3 S1 Pro. Any suggestions?
If you're using the Startup Optimizer plugin, try disabling it temporarily - it can occasionally interfere with the list of available printers. Should that not help you could manually re-insert the profile by copying this JSON into the appropriate directory (eg C:\Program Files\UltiMaker Cura 5.4.0\share\cura\resource\definitions).
