Ultimately, this is just my opinion about what apps should prioritize in terms of markdown. I don’t think it’s too much of an ask that these be consistent across apps. I’m not sure that there has ever really been an effort by the devs to standardize things in this kind of way. As I said in the post itself. Lemmy is no longer a baby platform. people have been sharing these best practices for markdown for over a year at least.
I think that when someone posts, they should have a reasonable expectation that people will see what they intend.
