I'm defining that aim as I go, basically. I'm trying to allow co-installation of the core packages; the framework and whatever of "plasma" I'll be able to port. As Jeremy pointed out, that is largely possible and intended because a gradual transition has been foreseen so that KDE4 applications can function normally "under" KF5.
As to applications: I'm not convinced that there would be much interest in having the KDE4 and KF5 version of all applications installed. For some, like KDevelop this can be justified for now, but for others it is probably good enough to be able to have either the KDE4 or the KF5 version activated at any given time. And then there is KDE PIM which shouldn't even be allowed to co-exist: it appears that one cannot go back (without risk) after having run the KF5 version.
Concurrent installation of the 2 "flavours" makes sense mostly if each of the 2 flavours has advantages that the other doesn't have.

Yes...

On the other hand, as I am under the impression that it is getting possible to have KF5 somewhat working within Macports (did not try myself), I also think that most useful thing for the users base at this point would be to include KF5 to Macports’ provided ports.

Marko is trying out a number of KF5 ports now. It would be nice if someone else could check the changes I've been making to KDE4 ports for side-effects that I have missed.
