Comment (by RJVB):

 That would work too, and it might be easier to test-build each of those
 qt5x-qtwebengine subports. Then again you can also argue that the CI and
 buildbots are there for doing that, esp. for something as huge as
 QtWebEngine but even the copy/pasting and managing any patchfiles required
 quickly becomes a monk's task (with such a big and complex Portfile).

 Initially I thought that qt5x-qtwebengine could be maintained (and provide
 QWE 5.x) for the purists but you're right that at some point QWE 5.1x will
 no longer build against Qt 5.9 . That could be handled with `replaced_by
 qt59-qtwebengine` if the active Qt version is 5.9, in addition to checking
 the OS version (which would limit the QWE version as needed). I can't
 really foretell what's best; I guess only practice can tell.

 Things are probably a bit easier with the rebooted QtWebkit for which I
 maintain a standalone port - for now at least.
