Should probably create a bugzilla issue for this. Takes too much time to casually look into.

ChangesList.php:                                return ' ' . $this->msg( 'rev-deleted-comment' )->escaped() . '';
EditPage.php:                           $data->log_comment = wfMsgHtml( 'rev-deleted-comment' );
FeedUtils.php:                          ? wfMsgHtml('rev-deleted-comment')
ImagePage.php:                  $row .= '' . $this->msg( 'rev-deleted-comment' )->escaped() . '';
Linker.php:                     $block = " " . wfMsgHtml( 'rev-deleted-comment' ) . "";
Linker.php:                     $block = " " . wfMsgHtml( 'rev-deleted-comment' ) . "";

There are already many bugs filed for revdel messages confusion due to bad terminology and what not: what to do?

Send a mail to wikitech-l (?). If you do, ensure to make an indisputable case.

Nooo emails to wikitech-l are something I completely fail at (which is part of the reason why I'm subscribed with delivery disabled). I was just wondering if I should add yet another "reword revdel" bug maybe with some tracking bug, or just add to an existing bug. Either way, it's bound to be a bit confusing, not a trivial task for a dev as you noted.
