Blank out remaining rev_comment fields on Wikimedia wikis
Closed, DeclinedPublic

Description

Judging from this query, many revisions from the end of February to October 25 on the English Wikipedia still have both a rev_comment_id and a non-empty rev_comment. We should start blanking out the remaining rev_comment fields on Wikimedia wikis that still have not been blanked yet by running maintenance/migrateComments.php once more on each wiki.

Talked about this with @Anomie, decided to decline. There are two potential benefits to clearing these out:

  1. Saving storage space.

Not considered important, because we're going to remove the column entirely "soon", which will yield the same saves and more.

  1. Hiding comments from WMCS replicas just in case there is something out of sync, given these columns are no longer meant to be used.

This is tracked as T212972, which will make these columns inaccessible entirely rather than just blank.
