I meant a separate source archive, of course.  That had nothing to do
with having the sources installed, let alone in some specific public
place.

No, it's much *less* reasonable.

Relocating things will not necessarily put them in ../src/ relative to
the binaries.  There's any number of other places, so the probability
of winding up in ../src is close to zero.
