Don't get me started on PowerPC after Apple. IBM has added so many new instructions in each new POWER version that today's ports of popular open-source code that generates code or needs to be bootstrapped from binaries (Node.js, Rust, Go, etc.) are often compiled to, or generate code requiring instructions that aren't in a G5's CPU. It's 64-bit PowerPC, circa 2004.
Not to mention that Linux on PowerPC decided to switch to little-endian because big-endian is such a giant code porting headache.
