Still not, because it is easier to copy/paste entity page URL (which is in the form https://musicbrainz.org/<entity>/<mbid>) from the MB website to enter the above replacement rather than to extract MBID and entity type out of it to enter [<entity>:<mbid>|name].
I concede that many tickets are very old, much older than my own involvement into this project. Worse, most tickets have not been clearly prioritized. I have just labelled the ticket you mentioned with low priority and good first bug, rather than won’t do since it is open to volunteers.
Last, current priorities are based last year MB user survey and serve the ongoing UX redesign.
