Well, this isn't natively part of bjam either. Its part of
Boost.Build. There are lots of files in $BOOST_ROOT/tools/build/v[12]
that make this magic possible and I'm sure considerable effort was
invested in their writing.

It is possible to build similar rule-sets using make as well (I know,
I've done it), but as Vladimir rightly points out the syntax is obtuse
and the end result not nearly as complete or full-featured. The
ability to produce both a debug and a release build with every
possible combination of features in a single pass is pretty amazing.

This along with the portability are the biggest win IMHO.

In the end I agree, but don't confuse the tool (bjam) with the
rule-set (Boost.Build).
