Continuous kdereview process
The kdereview process is a good tool to ensure that new applications meet some minimum standards. But it's a one-time thing.
Since standards change and code bitrots existing applications may not fulfill these standards.
It could make sense to periodically review existing applications to check whether they are still up to our standards.
I'm not quite sure how that could look like. Something like "Every week a app is picked and people look at it" or "Today we check that all apps have a CI build". Some of it can certainly be automated, other things would need manual checking
