It doesn't matter how many times you write this, you can not make it
become true. Brian keeps pointing out the simple case of an
intermittently connected network getting a different prefix on each
connect, but you keep ignoring it. STABLE ADDRESS SPACE IS A MAJOR
APPLICATION REASON TO HAVE SL. 

Also, as I have said multiple times, getting rid of SL does not create
PI space. When PI space is available, people will most likely recognize
that it is easier to deal with than SL, and will naturally migrate. Even
when it is available, that does not automatically create a reason to
restrict the use of SL. It will always be easier to filter a short /10
than to maintain a long list of access controls at the border. THIS IS A
MAJOR OPERATIONAL REASON TO USE SL.

It is appropriate that we have a document describing the impact on
multi-party apps using literal referrals, and another on guidance on DNS
configurations. We have discussed the first many times, and the second
is nothing more than formalizing what people have been already doing in
the face of 1918 space.
