Comment (by RJVB):

 You already decided you wanted to wait until the KF5 frameworks were in.
 The least invasive way to add a protection against installing `-qtonly` to
 my version in MacStrop is to add a small block somewhere high up enough
 (under the `test.run yes` line):

 {{{
 if {${subport} eq "${name}-qt5"} {
     if {![variant_isset qtonly]} {
         default_variants +qtonly
     }
 }
 }}}

 As to the GTk2 version version: yes, it's got a date in it. Purely
 historical; the GTk2 hasn't been upgraded since I changed the versioning
 scheme. It will move to that same scheme if I ever get around to it and
 figure out how to fix the regression(s) that were introduced after that
 Jan. 27th 2015 version. I've been meaning to do that
