It will be interesting to see how this plays out. I don't think that the RCC will be inundated by a wave of those availing themselves of this provision. Thus the few who do assent can either become part of an existing Catholic parish or have an “Anglican Rite “ Mass celebrated at various times of the day. The existing Anglican Protestant ecclesiastical structure will not allow those who accept this “Anglican Rite” to take the real property with them so the seekers will have to attend in existing Catholic parishes. In rare instances where there is a significant affluent number of those accepting the “ Anglican Rite” there might be a separate structure.But I can't see this as a norm.
I can see many of the current devout RC crowd seeking to join the “Anglican Rite” services as a protest to the “Novus Ordo “ which has been an albatross around their necks for the last forty years. Perhaps the current faithful remnant in the RCC could invite their “Happy Clappy Liturgical Abusing Crowd” parishioners to join the current Protestant Anglican crowd replete with with women and gay clergy. This would be akin to an exchange of POW'S after wars. Just some random thoughts.

There’s a whole group called the Traditional Anglican Communion, which claims 400,000+ members worldwide, that this is attended to accomodate.

They can start new churches the way everybody else does. Start meeting in someone’s living room. Move up to a school gymnasium or as secret guest congregation to an existing church. Get a strip mall storefront church. Buy some land, build a temporary church. Build a real church, use the temporary as a parish hall. Buy the surrounding land, kick out the neighbors. Build a school.

This was done for the Traditional Anglican Communion - not for some generic "here you go if you're interested" purpose. It's being rolled out in that fashion so as to soothe the shattered egos of the "official" Anglican Communion and the English Catholic clergy. It may become a model for others somewhere down the road but this is being done for the TAC and the TAC has no interest in the Anglican Use liturgy. They'll modify the 1928 BCP and the other uses based on that book if they have to, but I don't think there'll be too much of that.
