It's not for anyone in the RISC-V space, since it is defined by the architecture and used pervasively (and means the X register LENgth, i.e. how many bits in the x0-x31 GPRs). Using anything else in a RISC-V ABI context would be worse from a RISC-V perspective. In a random LLVM checkout I have I see 1118 instances of `/xlen/i` in llvm/lib/Target/RISCV alone.
