Why would that make you biased? Only makes you honest :-) And I agree,
partially.. IMO Jam servers reasonably well for the project specification.
It's simple and direct. But that's about as good as it gets.. Implementing
the build system itself in Jam was expedient at the time. But man is it a
PITA even with all the extensions we've done to it.

I think the C engine implementation is also holding us back. Each time I
start looking at the engine it takes me roughly a week to get enough
knowledge back to understand enough to then do something. There are
various ways to slice the system and choosing what each slice is written in
will require some discussion.

Indeed. But it is what it is. And all we can hope for is to find ways to
make domain experts figure out how something needs to be configured is
something we need to keep in mind moving forward. We know a heck of a lot
more about the varied use cases now than when v2 was designed.. And
certainly v1 was barely a start in this area.
