Let's say I click a user's edits, I see all his/her edits or her open edits.
I then used to begin to filter down the edits to progressively only see the wanted edits.
It is now impossible to begin filtering edits starting from a generic edit search page (entity/mbid/[open_]edits). ← the solution to this would be that clicking user/bob/edits/open would redirect to the appropriate complete detailed search URL (it was how it was done before) and same for /entity/mbid/open_edits → complete search URL ...
So that we can see current search criteria on top page
PS. Notice the inconsistency between /user/bob/edits/open and /entity/mbid/open_edits
