I've coded a 3rd party tool that could post to mastodon/twitter at the same time around 2020 (plenty of idle time during covid). I lost twitter API access, never bothered to try to make it work again (i hate working with interface clickers). to be clear, i don't really post on social media, it was just an experiment because i had faaar too much time and thought at the time that this kind of product could be interesting.

But i would bet social media managers use similar tools, and the fact that no one can access twitter API might add just the little bit of friction you want to avoid.
