> 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, ...).

Quoting cl-macs.el:

    [...]
    (defun cl--sm-macroexpand-1 (orig-fun exp &optional env)
    [...]
           ;; Convert setq to setf if required by symbol-macro expansion.
    [...]
