I was a bit skeptical of asking this question, since it seemed to be about style, which seems inherently opinion-based. However, there is a tag called "article-writing", which includes "style" in its description, and, this question isn't actually opinion-based. It asks about whether there's a consensus on whether a certain stylistic choice is unacceptable and/or whether it's uncommon.
This has an objective answer. The answer can be "this is acceptable and common", "this is not accepted and uncommon", "this is acceptable but uncommon", "there's no consensus on whether it's a good idea to do this, but most articles don't", etc. I'm not asking for anyone's opinion, I'm asking for what seems to be the mathematical community's collective opinion and what is common. These questions have objective answers, and due to the tag "article-writing", it seems that those questions are also on-topic. So, what then is the issue with my question? It has currently received 3 downvotes, but no close-votes, meaning I'm at a loss as to what I did wrong.
