Yes, we've been through that, indeed.  But it can be accomodated by
requiring the user to explicitly say that some TAGS file covers "these
and these extra directory trees" or to link TAGS file together.

The automatic suggestion could be restricted to only come about when
there is a TAGS file in one of the parent dirs.

Could be.  But etags has been around for a long time and was the only
"standard feature" of the kind until very recently in Emacs, so I think
it's fair to assume that there are more such users out there.
