Well, my thought is that last_oid is gone and it isn't ever coming back.
So the less code we use supporting a dead feature, the better.
If we can't remove the special case in EndCommand() altogether, I'd be
inclined to hard-code it as "if (tag == CMDTAG_INSERT ..." rather than
expend infrastructure on treating last_oid as a live option for commands
to have.
