Comment (by rjvbertin@…):

 I think I made my thoughts on this abundantly clear. There's nothing
 easier about moving everything in a single prefix as opposed to moving
 only the required bits to ${prefix}/libexec/qtN, and certainly less to
 debug because we already know where everything (else) is supposed to be
 located. And those are exactly the bits about which dependent code (as
 opposed to dependent build systems) may make assumptions.

 qt5-x11 is a perfectly viable runtime alternative, but I'm not going to be
 coming back to that.

 As to control freaking, I might simply break out my qtN-kde subports into
 full ports with a single maintainer (but will most likely keep them to
 myself).
