sure you don't need gtk2 and gtk3 or qt4 and qt5 ABI compatibility at
all--the fact they might co-exist under the same environment doesn't
imply you're allowed to mix both in the same process address-space--in
fact you can't mostly because there will be unrecoverable symbol clashes
and/or assert()ions that fail, not quite one of ABI incompatibility.
as a matter of fact, i see it all as a non-issue re. qt4/qt5 at least.
dunno about ardour and gtk2/gtk3 though, maybe that's the lurking
you have to realize that gtk2 or qt4 are phased-out and all systems will
be fully gtk3 and qt5 in the near future, a very near future on the qt5
front--on my watch, everything is already, there present, no looking

one can never say never but that is a very unlikely event to occur in
this universe where qtractor run.
unless someone gets ALSA-MIDI (alsa_seq API) fully ported to anything
but Linux :)
as said before too many times and again. all of (my) qstuff* including
qtractor and all the vee-ones, are there built on default to qt5
already. however there's still this configure --enable-qt4 option
avaialable for anyone who's stubborn enough to keep fighting on the qt4

and so that's why me as a developer, made the call. qt4 is dead. long
other's will follow as they will regret if they don't.
there's no way back in the progress of time.
not even for LV2 host/plugin UI developers :)
