See my previous message on this topic for my response to that proposal.

As well they should do so for their private use, c.f. RFC 2365.

Setting the DEFAULT multicast scope boundary at site-local would extend service provider private multicast beyond demarcations into their subscriber networks.  For that reason, service providers will certainly expect to use organization-local zone boundary edge routers for the same reason we recommend that residential gateways be organization-local zone boundary routers.

The first-mile link is an organizational zone boundary.  I don't understand why this is a point of such confusion.  Or do we really not like the idea that subscribers are separate organizations from their service providers?  "We are the Internet company.  All your base are belong to us!"
