You're playing on words here: we don't "already have" `r-p-d-s` on master.

Just because it's not a complex change doesn't mean it's "simpler" than
no change at all.

Yes, that's the starting design I had in mind (and that I described
a few emails back). it's also what we do in the byte-compilation case,
so it's code we already have and use.
The "en masse" doesn't make it complex.
