That's a misleading thing to say.

Time since an effort or discussion started has never been a guideline for 
when something is ready for CMake master.

I think you underestimate the cost of supporting old versions and the 
benefit of exploring the design space to get it as right as possible the 
first time (exploring the design space isn't the same as giving IDE 
developers votes).

I suggest switching gears and designing the initial protocol handshake and 
version negotiation, and come back to this buildsystem description part of 
the protocol later.

Designing the how versioning the protocol works can include design and 
discussion of end of support for particular protocol versions (how many 
years/releases it will be deprecated for before being removed etc). That is 
the first part that would get merged to master anyway.

Thanks,

Steve.
