@MichaelHardy You are misunderstanding what has been told to you. I don't know if this is a willful misunderstanding, or if we have simply failed to communicate effectively. On the assumption that it is the latter:
1) The edits which have drawn attention are things like changing dxdy
to dx\,dy
. Such edits are minor. Yes, it can be argued that they improve readability, and I would put forward that the thinspace is "more correct" (though I have seen it argued that $$\iint f(x,y)\, dxdy$$ is more correct than $$\iint f(x)\, dx\,dy,$$ as the integral the $dxdy$ should be understood as a single symbol---I disagree with this, but the argument can be made).
2) When editing older posts, edits should make significant improvements. Generally speaking, do not edit old posts for basic copy editing.
3) When editing any post, please do not make edits which alter the original asker's style.

Edits like those outlined in (1) are not significant improvements. In light of (2), they should not be made if it will bump an old post. They are also, arguably, a stylistic choice, and should not be made per (3).
Now, you are free to disagree---you clearly believe that these kinds of edits are of great significance. You are welcome to feel that way in your own personal writing and work. However, it is the opinion of the moderating team that these edits are not significant enough to bump an old post. As part of a more significant edit, great. If a post is new, great. But please don't bump old posts because you want to enforce your opinions about proper typesetting on everyone else.
(And, for what it is worth, I disagree with you, because the "correct" typesetting would be $$\iint f(x,y)\,\mathrm{d}x\,\mathrm{d}y, $$ But I don't enforce my subjective opinions regarding good typesetting on others.)
