One aspect of moving to Python is that more people are in a
better
position to understand the build system.

Of course. But we aren't talking about removing any
functionality to the
existing system. Only incrementally reimplementing the
non-bjam BB
layer, on something other than Jam.

That is an unfair comparison. As I've said in my comments
about
meta-make systems... To make it fair you would have to
consider the
comparison between Boost.Build + Python + bjam and
Boost.Build + Cmake +
nmake + VS + gmake + bsdmake + make + Xcode + etc.
