I just merged alla the Rowlings (:​D) and noticed that on an old page (https://beta.bookbrainz.org/author/2a678ff9-86e3-418d-af40-3cfb4eb0ad43 the link to history https://beta.bookbrainz.org/author/2a678ff9-86e3-418d-af40-3cfb4eb0ad43/revisions ) redirects to https://beta.bookbrainz.org/author/14fcaca2-7380-4272-846a-c8dc5f539b33 not https://beta.bookbrainz.org/author/14fcaca2-7380-4272-846a-c8dc5f539b33/revisions
(minor, but old bbid/something should redirect to new bbid/something, for example for old revision notes, community posts etc. so they get redirected to the right place right away without people having to guess, click twice or edit urls)
