Add a "teamspawns" and "noteamspawns" feature to gametypefilter. I believe this is useful for maps that filter entities when team spawns are used. It can avoid adding each gametype manually in entities, and updating maps if a gametype is changed or added in Xonotic. I know about the "teams" and "noteams" switch, but these ignore team games that don't use team spawns and therefore a red / blue base (like TDM or DOM).
