So far I've been using just MO_UB and MO_SB for in situations where we want a 1-byte memory op, without the XE prefix, since the endianness doesn't matter. r~

That said a common problem with this short MO aliases is that there is no consistency in the naming, on one side with the endianness for bytes, and on the other side with the signedness for quad words. The same way, if we wan to use MO aliases for the stores, we end-up specifying a useless endianness. Anyway I'll drop that for now and submit a new version of the MIPS patch.
