The idea that compiling your code for 68000 or MIPS can reveal bugs in your code does not change the fact that x86 and ARM are pretty much the only relevant CPU architectures that all but the most entrenched of government contractors could ship a product on today or in the foreseeable future that would have any use for SIMD. If you actually have a need to do extensive SIMD optimizations (say, it could shave 5ms off your frame time in a game, or save you $XXXXXX/year in your data center), PowerPC does not enter your mind at any moment.

You see it as weeding out bugs and future proofing your code in case x86 or ARM disappears tomorrow, I see it as a load of completely wasted work and optimization opportunities.

Also lowRISC learned nearly nothing from the past 20 years of CPU architecture advancement. It is not modern, it is a naive copy of a very outdated design.
