Hi,

Given the timing (no spec approved) it sounds like a v2.1 plus
microversions (just merging) with no v2 changes at all.

The v2.1 framework is more flexible and you should need no changes to
servers.py at all as there are hooks for adding extra parameters in
separate plugins. There are examples of this in the v3 directory which is
really v2.1 now.
