Not sure I can help.

In CL, all the p?set[qf] handle symbol macros.  I haven't tested this,
but from doc strings I'd say none of these supports symbol macros in
Emacs.

There is also an intricacy here:

Setq, with CL behaviour, would behave like setf for symbol macros.  And
setq is in C.  I don't know if maintainers would accept such a change in
C (performance, dependencies, ...).
