probably it would be there if there was more activity in Africa in OSM. Usually we don't accept deletions because a feature is not yet mapped elsewhere. I am opposing the idea to remove the "default" landcover.

In this case we could then split the relation into smaller parts like we also do with forests or other huge mp.
I generally like the idea to import data for the Antarctic and am not against deleting very rough coastlines or other data there (with the intent to replace it with more accurate data by import and with the old data coming from previous imports), but you shouldn't delete "correct" mapping and you should pay attention to the (maybe existing) manual refinements and mapping in the area (I.e. keep it). It is a really huge region and while there might be a lot of fun and none sense objects there might also be some treasures.
