Doesn't sound particularly simple to use (can you say "usine a
gaz"?), even if it is "relatively easy to implement".  But I admit
that I have only a vague notion of what you have in mind.

While waiting for your implementation of that multifaceted feature,
perhaps we can adopt the simple change I suggested? (A bug fix, IMO.)

But again, I'm OK with just continuing to use the fix in my code,
if Emacs doesn't want it.
