RFC 9112 Requirement

Section: 7.3-5 Keyword: SHOULD NOT

The TE header field (Section 10.1.4 of [HTTP]) uses a pseudo-parameter named "q" as the rank value when multiple transfer codings are acceptable. Future registrations of transfer codings SHOULD NOT define parameters called "q" (case-insensitively) in order to avoid ambiguities.¶
