Speaking of which, RFC 9111 states in 
<https://greenbytes.de/tech/specs/rfc9111.html#rfc.section.4.p.3>:

 > Note that a cache extension can override any of the requirements 
listed; see Section 5.2.3.

which is about Cache-Control.

Was it ever considered to use Cache-Control here? (yes, I understand the 
parsing issues) ... in any case, a short statement why not might be good.

Also: maybe make it clear upfront that the spec really defines a "Cache 
Extension", as described in Section 4 of RFC 9111 (and use that in 
Section 7, which brought me here...)

(let me know if I should suggest text)
