That is true, as far as subrepos work _today_, but I don't think there
is a reason why things could not be improved to a point where this is
no longer true in many cases.

In fact, once you understand why you should always use relative
subrepos (unless you have a very good reason not to), then a lot of
the problems and confusion that people have with subrepos disappear.

I would say that there is a compelling argument to be made that you
should be able to setup subrepos on the .hgsub file as follows:


And have it be equivalent to:

subrepo1 = subrepo1
subrepo2 = subrepo2
subrepoN = subrepoN

That way people would be far less likely to configure (and thus use)
absolute subrepos.
