What's a good way to go up one header / section?

[Crissov]

I’ve suggested before to (optionally) treat the three different kinds of “thematic breaks” as various kinds of section breaks:

Horizontal rules as (hierarchical) section breaks etc

When Markdown was devised in 2004, there was no HTML5 and hence no <section> element type, just <hr>. Should a modern implementation (per user-select option or extension) treat one or all “horizontal line” markup as section breaks? Should it introduce new repeated character lines instead, e.g. ====, ####, .... or ''''? # First chapter ---- # Second chapter <section> <h1>First chapter</h1> </section><section> <h1>Second chapter</h1> </section> Paged media Slides For slide-based presentations…
