The Umbrello/kdevelop problem

[Albert Astals Cid]

KDevelop & friends just migrated to KF6-only in time for the KDE Gear 24.08

Unfortutantely we collectively forgot Umbrello uses KDevelop stuff too and 
Umbrello is in KF5.

It compiles locally fine without kdevelop (with loss of features I guess) but 
it's failing on CI 
https://invent.kde.org/sdk/umbrello/-/pipelines/737657

Which features are lost in Umbrello when kdev-* is not available?

For 24.08 would it make sense to just copy the necessary kdev-* code to 
umbrello or that's crazyness?

Is an umbrello KF6 port in sight for 24.12?

Cheers,
  Albert
