Aren't these MCUs predominantly ARM-based, with some RISC-V thrown in?
I see no contradiction in the desire to support x64 (because it would be ridiculous not to), ARM, and likely RISC-V, but not the venerable but now-fringe architectures like MIPS or Sparc or 68040 or even x86.
The author can do whatever they want. But if all you want to support is x86-64, ARM64 and maybe some version of RISC-V, don't crow about how 'extremely' portable you are. At best, you don't know.
portable is a different word from ported.

For those not in the know, Microchip still produces MIPS microcontrollers:

AfAIK lots of 8051-based microcontrollers that are quite modern, such as Silicon Labs EFM8 line[1] or STC which in addition to 8-bit 8051's also has 32-bit 8051 variants[2].
