Important question, are the KF5-versions of those libraries co-installable 
with the kdelibs4-versions?

I don't think that is on the plan for us, the KDE Applications 15.12 schedule 
starts much later
https://techbase.kde.org/Schedules/Applications/15.12_Release_Schedule

If the libraries are co-installable with their kdelibs4 counterparts and if 
digikam 5.0 final is planned to happen after we release KDE Applications 15.12 
I guess you could release an "unofficial tarball" of those libraries clearly 
marked with a a weird number like 15.11.55 or something, with the 
understanding that you'll stop releasing those applications after the KDE 
Applications 15.12 release (assuming we decide to migrate those libs to KF5-
based, which i guess makes sense).

Cheers,
