I'm still confused by the purpose of this paragraph, it opens with discussion of the header (emphasis mine):

> An HTTP/3 implementation MAY impose a limit on the maximum size of **the header** it will accept on an individual HTTP message

Since the rest of the paragraph discusses SETTINGS_MAX_HEADER_LIST_SIZE it seems that the limit only applies to the sum total of all header fields in a message. It is not possible to express the maximum size of a single header field. If so, we should change the wording slightly to make this clearer.
