Can you share your reasoning behind the tagline? It seems like a hard sell, which doesn't necessarily help the otherwise gorgeous looking website and solid-seeming API choices. Like;

  JWT-Based Authentication: We won’t support JWT-based auth unless provided by a third-party plugin.

Right there you've missed something that, say, next-auth covers natively + extensively. What kind of "comprehensiveness" are you targeting?

EDIT: Wow, just want to double down on the "gorgeous website" comment after clicking through your docs. Well done, inspiring work! Clear, concise, and eminently navigable.
