it is in the sense that those are programmer conveniences only for assembly programmers and Riscv's view is that to the extent possible the assembly programmer interface should largely be handled by psuedo-instructions that disappear when your go to machine code rather than making the chip deal with them
Sure but that's not necessarily at odds with "programmer conveniences or other such cleverness" is it?
