Hi,

for applications I agree to drop Qt5 CI. The few usages that are left 
either already have Qt6 CI, or are more or less dead projects.

That said, we have a number of (Plasma) components that we still build 
for Qt5 for (external) application compatibility (breeze, 
plasma-integration, etc). So far we have not made a decision to stop 
doing that, and I'd rather not lose CI for those. That doesn't mean we 
need Qt5 CI in the current form. Could we use a distribution image with 
Qt and the few necessary libraries/frameworks baked in? That would be a 
much smaller image and easier to maintain than the current suse-qt515 
image.

Cheers
