In that case why not have said that Boost libraries and tools will be
supporting CMake, which I think is fair enough given the wish to form a
consensus, but that Boost Build will continue to be developed/supported
for those libraries and tools that still want to rely on it as an
alternative. Given that we have people like Rene, Steven, and Thorsten,
among others, who still work to improve Boost Build, I see such a
decision to give up Boost Build entirely for CMake, before we even know
if we can actually duplicate all the functionality which Boost Build
provides in CMake, as a bad decision.

I am not against providing CMake for the user community at large, but I
just don't think we should be throwing Boost Build away.
