Primarily WikimediaMessages, but some other extensions (GlobalBlocking, GrowthExperiments) use MessageCacheFetchOverrides too...
But it'd be useful if there was a way to annotate (CSS/similar) overridden messages (though, ideally local overrides) and make them obvious, at least in a developer UI.

| Show overridden message keys when using &uselang=qqx | mediawiki/core | master | +19 -2 |
I've been doing some cleanup of the core signup code (change 1025832) and I found T214135, which also complains about this problem; then I found your task when looking for some other feature request about it. I think it's a great idea.
Not that long ago, I extended the output of uselang=qqx to display fallback message keys (T300069). I think the same approach could work for the override keys.
