Quite a number of people (Rene, Edward, myself, ...) have argued in
different ways against a wholesale switch from Boost.Build to CMake.
While for some the point is more about incrementality of the process,
for others it's about autonomy and modularity.

I'm surprised, even shocked, to see that your draft doesn't even mention
modularity as a goal, but again focusses exclusively on the modalities
of an eventual switch. I have said it often, and I'm saying it again:
you can't force a Boost maintainer to adopt a CMake-based build system
for his project. You can only show by example that it works well (by
picking volunteer projects as early adapters), and hope for others to
follow voluntarily (incrementally over the course of a couple of
releases), given that the maintenance burden of that new environment is
entirely on them.

So, I would expect in a RFP to find requirements such as:

* a solution must allow for a heterogeneous environment, where some
Boost libraries are still built with Boost.Build, while others are built
with CMake.

Anything less than that is not going to fly.
