I remember it was mainly about performance. I actually have a repo on 
GitHub which has a version of Kicker that runs on Qt4/KDE4. I also 
remember Tim had Trinity mostly working against Qt4 but he saw a lot of 
performance issues.

Having a Trinity-like DE on Qt5 could probably mostly be achieved by 
porting just Kicker and KDesktop to Qt5/KDE5 and having a session with 
those instead of Plasma. That wouldn't make sense if performance would 
suffer significantly though.

There was also the recent announcement about Qt Lite. It's supposed to 
run on systems with as little as 16 MB of memory and doesn't require 

Maybe these developments are out of scope for the Trinity project 
already, but it would be interesting to hear if anybody had compared 
them with Qt3/TQt.

Best regards,
