Having PUIDs(historic) in the edits history have no benefit anymore whatsoever. Nevertheless they still clog the history, making it hard to read sometime and eating along precious server CPU cycles and space. One exmample among so many: https://musicbrainz.org/recording/728cff82-8b98-4909-8303-d9ff5e37a246 you can see pages and pages of PUIDs edits at the end of the history.

Could you prune PUIDs(historic) from the tables?

Thanks in advance.
