Hardly on topic for this list, but yes that's exactly what it means, and
what it was intended to mean.  It's no big deal for a client to generate
the header field, so it's hardly onerous!  (see this message for an
example of a compliant client)

What it does for you is to ensure that if you are corresponding with
someone whose client is MIME compatible, you learn that is so "for free"

You might note that adding "MIME-Version: 1.0" to a message that is
otherwise "not MIME" (but correctly eschews the use of "non-ASCII"
characters etc), will make no difference to its interpretation.
