If the only toolkits which could do it are non-free or "insignificant", then
I agree, but otherwise it may still make sense to provide it as
a toolkit-dependent optimization. But indeed, it means that even if we
manage to change it for some toolkits, you won't be able to rely on
your :filters and :enables being called only when strictly necessary.
I've always viewed such a change as a performance improvement for those
cases where we use large dynamically-generated menus or menus with lots of
shortcuts to compute (X-Symbol comes to mind).
AFAIK XEmacs does compute menus on-demand.
