All versions of Emacs I can think of have `set-keymap-parent`, including
Emacs-19 and XEmacs. Why not just always use `set-keymap-parent`?

Why not, indeed? I wasn't aware of the existence of `set-keymap-parent'
in XEmacs until you pointed it out. The preferred form in XEmacs is in
any case `set-keymap-parents', the singular form being in a file called
"obsolete.el".
Anyway, it doesn't seem to be a big enough point to be worth raising a
fuss over.
