On other stack exchanges, I can edit my comments (albeit for a limited period of time). Why can't we do it here? I find it even more important here than in other SEs because I use a lot of LaTeX and too often it's not obvious at first whether or not the LaTeX will "compile" properly (no missing brackets, dollar signs, etc.). I find the LaTeX error after posting the comment, and find myself having to delete the comment and start over again.
I see why we don't want users to be able to edit a comment 5 months later after 100 people have replied to the comment, and then the original commenter changes their mind. But is it not possible to allow edits for 15 seconds?
I have given a screenshot of what my comments look like:
