It is technically possible for local administrators to delete certain revisions but it's really not recommended at all. Edits from history should never be removed - even if it's spam/vandalism. By deleting edits you take away the transparency of what's happening on a community.

The only exception I think would be legal/privacy issues by Fandom staff. Vstf can't remove entries from history though. Not in the form of "deleting" them. They have access to RevisionDelete but that only crosses out the edit. There is still a footprint left behind with that method. It is also not purview for vstf to utilize this ability without the permission of Fandom staff.

Fandom staff (with utility rights) have access to  and this is probably the closest you would get to "deleting" actual entries from history as if it never happened.
