    I think all it needs is something along the lines of "This BCP applies to TLS
    as used on the public Internet [Not part of the text but meaning the area that
    the IETF creates standards for].  Since TLS has been adopted in a large number
    of areas outside of this, considerations for use in these areas are left to
    relevant standards bodies to define".
 

I think it should be phrased the other way, as in
	There are some environments (e.g., a network which has no connectivity to the public Internet), where this BCP need not apply.

I don't care what the wording is, but I think the right way to approach this is to carve out an exception for those who will be upset by the recommendation.
