That is an orthogonal problem. If we agreed to merge some 
collections library to Phobos, it could be done to Phobos 1 just 
as well. We don't need Phobos 2 for that.

Rather Phobos 2 lets us to discard some old design decisions we 
don't want to keep around anymore. Autodecoding is the best 
example, but not the only one. Were we simply to drop that in 
Phobos 1, it would be far more difficult to migrate for users.
