PowerPC at least still has a living ecosystem, even from the bootloader level. GRUB can boot from an OpenFirmware system. There's also yaboot if you hate yourself. ;)

I would personally love to see more Power Systems based projects. Everything is out there, just someone has to want to do something with it.

Fedora Linux even fully supports POWER8+ little-endian systems, and Fedora KDE offers a live ISO you can install on something like a Talos Workstation.
