I disagree unless we really want to enable http-equiv as a way of
specifying browser-only HTTP header equivalents that intermediaries
ignore.
Sorry, my statement was ambiguous. To be more specific:
"I think the HTML5 requirement should be changed to allow any header
in the Permanent Message Header Field Registry to be registered as a
pragma extension (instead of only headers defined by an RFC)."
I think this has no impact on your point of concern.
OTOH, if we want to enable only pragmas that the HTML layer must
recognize for backwards-compatibility, enumerating the permitted
values is quite reasonable.
Are you suggesting that the pragma extensions registry should be
removed entirely?
