Why aren't twitter facebook and last.fm on the services page? [Explained]

Twitter facebook last.fm dropbox tidal. Shouldnt they all show up under services section in settings

twitter/facebook/last.fm are all tied to a profile

dropbox is system wide because it is only for backups

tidal is system wide because it is related to content (which is not per-profile)

Right. Since we only use one common profile I didnot think about it. Thnks
