Please remove horrible Flemish translation
Apparently F-Droid now includes a translation in Flemish (Vlaams). Officially there does not exist any Flemish language, it's actually the same as Dutch. So nl-be locale should just use the same translation as nl-nl.
Now the problem here is that the Flemish translation being used, is some kind of dialect often called "tussentaal". It is something between official Dutch and real local dialects. It is not an official language, and is used mostly in spoken language, rarely in written language and basically never in formal written language.
I have never seen this language being used in any software and it looks just... awful. It makes F-Droid appear like a very low quality application written by someone who cannot even properly use its own official language. Please remove this translation completely, or make sure it is never used by default on user's system. Of course it looks also completely out of the place in Android's correct Dutch language user interface.
