I do not think I have ever used the self moderation feature, but there is no call for it to be removed and you do not really need to stress yourself amplifying the opinion if you do not agree with it. The statistics of posts which are created self moderated is not much, not nearly enough to cause a forum issue even if it was being commonly abused (which it is not).
I think the request to ban self-moderated won't happen as the person who requested it is a troll who doesn't deserve the attention of such issue.
The request will be rejected on merit of the argument and not the user that made it, or so it should be.
