For some reason I'm pretty sure that we had this at one point, but it might have been a userscript that I was using.

One of the reasons I prefer Wikipedia articles over MB artist pages by far is that they show the associated acts right in the infobox at the top. For artists that don't have any/many solo releases like https://musicbrainz.org/artist/d6228c97-5b2e-47d1-8d99-06bf7484be54 or https://musicbrainz.org/artist/7f4195a2-c1ce-4dae-bbbc-3f5967f077ec on Wikipedia I can directly go to the band pages, on MB it's one more click.
