Not what you were offering so feel free to ignore this, but I'm super curious about RISC-V. Do you know if any serious attempts are happening to make RISC-V based systems? And if not, do you know why? Is it too raw/un-polished?

Yes, it has no licensing fees, and its being used in pinepen, some small electronics like calculators, and do you mean dev kits like this? They are arduino like devices with low power edge AI/neural capabilities. https://www.seeedstudio.com/sipeed
On linux, they are making one with an allwinner chip called the D1. https://www.hackster.io/news/sipeed-teases-linux-capable-64-...
RISC-V is not inherently better or more secure, its a different instruction set with no fees, so anyone can make one, its possible to be less secure.

RISC-V probably has the most "serious" effort of anything other than ARM and X86.

That's a fair estimate, but let's not forget IBM's Power architecture.

Power is very cool and I want a Power10 box a lot but I'm not sure if it's fair to really decide in it's favour because POWER is basically unobtainable whereas you can actually buy dev boards for RISC-V from SiFive.
