That just leads me to ask what's missing from the bjam core that we
can't implement the same behavior without resorting to extending bjam
specifically for response files?

In the near term, we'll keep the same build engine, so nothing much
will happen. In the long term, we might use Scons' build engine, but
that's just Python. We can extend it (if necessary) to do anything we
like. However, I'd like to answer the question I posed above before
thinking of making that extension. Response files don't seem like
such a special case that they should require their own build engine
