Here's Brevoort's response to my question to him on Tumblr:

Q: Do you have control over the reality designations for Marvel? In that case, are any designations planned for the many realities in X-Treme X-Men?

A: I could if I wanted to, but it’s really not something that I worry about. And every reality gets a designation, typically assigned by the Handbook writers—so yes, when that material is summarized in the Handbooks, those worlds would get names and numbers.
