Styling is a big part of it, but so is semantics...it's not ALL styling.

Historically - authors aren't too concerned about piddlin' little things like promotions, grammar, punctuation, spelling, conciseness, story continuity, etc. let alone font size and other stylistic issues. That is what the editor/publisher was paid to do.

Regardless of whether the author cares about this stuff, this stuff is there, and there are standards for their use.

I understand that 98% of people currently don't use accessibility functions but who knows if the next version of Covid will make 98% of the Earth's population blind (wasn't there a movie about that?) in the next 5 years....

The point is, publishers should be following the standards for publishing, whether they are a big publisher or an indie author. "We've always done it that way" or "We're a big publisher so we don't care about xxxx" or "Typewriter's historically didn't have the ability to xxxxx" isn't really a valid reason to NOT follow the standard.
