The good news with installing the now-concurrent version of port:qt4-mac plus qt4-mac-transitional is that nothing changes from the point of view of all your installed Qt4 and KDE4 applications. They only need the Qt4 libraries, and they'll find them (just through an additional symlink).

We're talking about header files here. They're used only when you build software, and that bite in your bum will be very easy to diagnose and remedy (= reinstall the headers). Linux systems do this systematically nowadays: you only install the headers for things like Qt when you're going to do development.

I'm not sure we need XDG*_HOME? I thought I'd compared the locations generated with my latest patch with the ones I get on KUbuntu 15.05RC (with the Plasma5 desktop), and they match.

Which is what I'm continuing to do.
The real alternative I see (but too formidable a task maybe even for "the all of us") is to make a new Trinity desktop. FYI, Trinity is KDE3 continued. In this case we'd be talking about porting KDE4 from Qt4 to Qt5 as an alternative to KF5. I'm a bit surprised that I haven't yet caught wind of others considering this, but that might only begin to happen once enough people who don't like living on the bleeding edge find themselves putting up with a desktop environment they no longer feel at home in.

No, eventually we'd have too many issues building Qt 4, and that might happen sooner on OS X than elsewhere.

What's with Konqueror?

I think I already mentioned this in this thread, but those are indirect dependencies. Build dependencies if you like, like the dependency on GTk2 and GTk3 I noticed in some KDE4 ports because they depend on (X11 independent) libraries from things like ImageMagick which also provide X11 functionality. It doesn't mean you have to have X11 running when you run your KDE application.
It does mean that users will potentially have to sit through the build of huge packages if they cannot be distributed in binary form.
