When did MTRACE come in? My recollection is that it was one of the
Selectable Units for OS/VS2 R3.8 (SU 33? SU 64?).

I think it's safe to say that MTRACE is older than many members of this list...who I'm sure won't recall the SU bit string or SUs. I recall that MTRACE was there by MVS 3.8 SE2, but I can't vouch for it being present further back than that.
