Yes, I do in fact envision two languages here and this thread is about
the implementation, NOT the usage, i.e. the target-declarations. So if
you only use the features provided by the system, you'd neither need
python nor C++. But if you need an extension you write in in Python or
C++. I.e. if you have a small one, use python, if you have a big one
(e.g. Java) use C++.

So if I start a new project and I want to use Boost.Build for it, how
many languages do I need to know to write the build system ? (I'd find
anything other than '1' unacceptable.)

I think the answer depends on whether people will like Python syntax
for declaring targets.
