I feel like "NOT intended" is even understating it, so I'll quote your other post:
"Code using Zcmp or Zcmt is incompatible with the RV64GC ISA assumed by current Linux etc OSes as it redefines and reuses the 16 bit opcodes for double precision floating point load and store. Full-size instructions must be used instead."
I'm amused that the instructions that get the best compression by far, multi-register push/pop, are also the instructions that are too much of a pain to bother with on large cores.
