To be fair, I believe the failure wasn't in building boost but in building
the jam log processor, so it does make sense to disconnect that from the
boost->build relationship.

I really feel like we've had this conversation before, and there was a good
reason to set it up like this. Unfortunately I can't find the chain on

Regardless, it seems like having the defaults in boost build be something
that depends on a specific feature in boost is too aggressive. Would it be
possible to put this feature on some kind of flag (default off) until the
features it depends on have been in master for a while? Is this something
that could hit other users of boost build who may be using it for non-boost
