Yeah, very much legally distinct MIPS, at least as a starting point.
The biggest tell is the mnemonics. While RISC-V takes a bunch of ideas from other places, and cleans things up, it copies a lot of mnemonics straight from MIPS.
But it also copies a lot of other ideas from MIPS, like the absolute distain for flag registers.
