Clients, no, because they only deal with existing commands.
Servers that are broken by it aren't sufficiently defensive.

Note that message IDs are limited to 250 characters including the < and >,
while command lines are limited to 510 plus CRLF.
Okay, so the proposed wording (having seen your later message) is:`
A "keyword" MUST consist only of US-ASCII letters, digits, and the
characters dot (".") and dash ("-"), and MUST begin with a letter.
Keywords MUST be at least three characters.
keyword = ALPHA 2*(ALPHA / DIGIT / "." / "-")
