I do follow your reasoning, bad comments are worse then no comments, but in this particular case it really feels to me like the meat of the commit body should also be a comment. Just so that when someone looks at the code and wonders, hmm, why is this flag here, he/she can figure it out without having to do a blame/log on the file. (Don't get me wrong, great tool, but has it's own problems).
Judging whether or not comments are permitted on the bitrot-ability of a piece of code seems hard to begin with, and even then a bit arbitrary. In this case, the whole comment would be just for that flag. So if someone really just gets rid of the flag but not the comment, especially on code like this, and that also passes code review then I think there are more pressing problems then bitrot.
