You're right -- it's not an argument. It's a historical observation. If there is an implied conclusion in there, my intent was that it be something like, "It's a little unfair to vote something down on aesthetic grounds when the original (and still AFAIK most explicit and authoritative) statement on the community aesthetic allowed such posts".
Okay, this reveals my misconception of your comment, but here again I disagree for pretty much the same reason and with the same reply: aesthetic judgment is very important (as in: it's an aspect of preference, and beware trivial inconveniences). It's only something to discard if opinions differ so wildly as to make the negotiations worse than dropping the matter.
