I love hobby platforms like 68k, but I definitely agree with you.
It's become unthinkable in the open-source world to not have "one X to rule them all" (in this case X happens to be "compiler", but you see this effect with other tools).
Hobby platforms, especially long-dead ISAs like 68k, should be easy to integrate with LLVM (perhaps through a plugin system? I'm pretty sure both GCC and LLVM have that... you install `gcc` and then you install `gcc-platform-x` or something...) but requiring LLVM core maintainers to think about your obscure arch is not worth it IMO.
68k is not a long dead ISA. Coldfire (68k ISA based) MCUs are still manufactured and used in products. Yes, NXP is pushing ARM instead now, like everyone else, but there is still hardware out there that needs software.
