> Now the only "correct" way is a slew of media queries to set some designer's idea of the font for every possible viewport size.
Nested H1s was never semantically correct in the first place, at least for accessibility purposes.
You can do flexible sizes without media queries (eg, viewport size units + clamp). Designers generally understand the web pretty well these days.
I only see one situation where people might have depended on these styles, but it's a big one - anywhere that you output the plain HTML of a "rich text" component from a CMS or whatever. There, if the stakes are low, it might not have been a big deal to just let the browser do it and headings might look too big sometimes now.
