You suggest to the port author to have emacs be the default and

library or file that indicates the presence of either, you could
use the
"lib:" form of dependent specification that would accept either
version of
emacs. It doesn't check for a port but a library of file. The ports
depending on X11 do this so you can either use Apple's X11 or the
one from
MacPorts. Like this:
lib:libX11.6:XFree86
Am I naive to propose that, in the case of something system-
supplied like Emacs, the dependency be omitted?
For Mozart it turns out I can override the default (emacs) by
setting an environment variable (OZEMACS=xemacs). Everyone can do
this, so IMHO the dependency on MacPorts emacs should be dropped.
I don't know about the specific case of emacs, but in general,
MacPorts prefers to use its own software in preference to system-
supplied versions; see the FAQ:
