Comment (by RJVB):

 Want, want, want ... my point is a bit that we don't yet have a clear
 picture of what we want ... in terms of best compromise. I think it's best
 to keep things as simple as possible, and for now that might indeed mean
 not bothering with a port that doesn't yet exist.

 The main thing now is to have a qt5.depends_component function that works
 for your port so that dependent ports can start using it to ease the
 integration of port:qt5-kde. In the future that function can be refactored
 as needed so that it works with all possible Qt5 ports, without changing
 the API of course.

 One thing I didn't check: did you foresee a way to pull in your meta-port?
 My proposal did that with `qt5.depends_component qt5`, and that syntax is
 in fact used in port:py-pyqt5 (with a minimal embedded copy of
 qt5.depends_component). In my mind this means "all of Qt5 except WebKit
 and WebEngine" because they're so big and the latter is a replacement of
 the former. But we could also agree on `qt5.depends_component all` which
 would include all subports.
