But I think that many more users would be needed to make it worth implementation at this point, as I would say that not many would use it or at least, keep it consistent.
No additional users are required to improve typography.
Not to add few more options either. A better looking content view could do wonders in signing up more people. Although it may be a lot of work to switch to for example Markdown Extra, which WordPress markdown is based on IIRC since that's an implementation on chain level.
If I scroll through for example Mix, it is difficult to share Hive because we look so... outdated.
Then again, I'm not too big a fan of too many options either since too many people think they know what looks good but most of their type styling creations will be only good to smack them in the face with. ¯\_(ツ)_/¯
