Replicating ports is a different problem space than replication ports?
If we end up with a bunch of different little half-assed extensions for
the same thing, then the extension FUD is right.

If there are real, actual, concrete reasons why doing something is very
complex and probably not useful, that's another story, but I don't think
that's the case here.

A mixer usually has several 'strips', each of which may have different
counts.  Like the ardour mixer, for example.  This is a simple,
realistic, and useful case where simply having a single global value
doesn't cut it.  The same goes for virtually anything with several
signal paths.
