Comment (by spacedmonkey):

 Looking into it, there isn't any documentation for why it was added a non-
 persistent cache group add here #6740 .

 Looking into the delete / update functions already has clean_comment_cache
 function calls.

 I ran all of the tests for the comment group and nothing fails. I have
 added a patch, that is pretty simple.  I will work on some tests later.
