I like this boiler plate wording a little bit better than what is in draft-leiba-rfc2119-update.
I think it will better end the ambiguity as to whether lowercase is intended to be normative within the document.
However, I’m not convinced it will reduce the amount of discussion as to whether a particular use of one of these words in a document should have been written in ALL CAPS.

Requirements Language
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" are to
be interpreted as described in RFC 2119 [RFC2119] only when they
appear in all upper case. They may also appear in lower or mixed
case as English words, without normative meaning.
