Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Minix
If you're willing to go REAL slow, there's still FPGAs. Something like this perhaps. Adoption would be pretty damned limited though, so your point stands.

What is a list of all softcores that were designed purely using VHDL?
I used this one https://github.com/lxp32/lxp32-cpu as base for building a RISC-V softcore.

Microwatt: A tiny Open POWER ISA softcore written in VHDL 2008
My favorite part of this project is the pretty large battery of test cases. A lot of chip rtl releases don't bother with open sourcing the verification too, and that's arguably more useful than the rtl in the first place.

RISC-V Pushes into the Mainstream
I have several OpenPOWER systems, including the POWER9 I use as my usual desktop. Besides IBM and other server manufacturers like Tyan and Wistron, you can get them as Raptor workstations and servers.
If you want an OpenPOWER design to play with, look at Microwatt ( https://github.com/antonblanchard/microwatt ) which is complete enough to boot Linux.

How long until RISC gets adopted for the desktop?
Not true, as of 2019 the power ISA is able to be used without needing to pay any royalties to ibm under the openpower foundation. There's already a few projects that have taken advantage of it such as libreSOC and Microwatt. Source code for various firmware components are also freely available pertaining to the power platform.
- Any raw binary generic platform-agnostic test roms for PowerPC?

Keeping POWER relevant in the open source world
At the other end of the scale, if anyone wants to play you can run a little openpower CPU on a FPGA with completely open source. https://github.com/antonblanchard/microwatt
It's capable of running Linux, some example docs are https://shenki.github.io/boot-linux-on-microwatt/

What is your take on ISA architectures for FPGAs (x86, arm, risc-v)?
Why dismiss POWER or SPARC ? :-)

OpenPOWER Foundation announces LibreBMC, a POWER-based, fully open-source BMC
An OpenPOWER one, likely this with modification: https://github.com/antonblanchard/microwatt

Exploiting Undocumented Hardware Blocks in the LPC55S69
You might be interested in what Anton Blanchard has been up to with the power ISA soft cores, it seems like his work has spanned the bulk of the FPGA toolkits, and I think his latest is taped out for the SKY130 run. His work is also being adapted for an openBMC replacement, which would offer an opportunity to dust off some old Xzibit templates, so thats good.
