We have switched back and forth on this because we also wanted to stay as close to Markdown as possible, just for the familiarity. However, the fact that Typst also uses the hashtag to indicate an inline expression led to too much confusion (`#thing` was a variable access and `# thing` a heading). And the hashtag is really quite nice for these inline expressions, so it won over the headings. Using `=` for them does have some precedent with AsciiDoc.

Definitely a lot of precedent for `=` for headers:
