At minimum the trunk of BBv2 has to work with the release of bjam. It's
why we have a bunch of version checks, feature checks and alternate
implementations of BBv2 code. Anything else would make bring it back to
the horrible days of yonder past where users could not test, use, or
otherwise operate with current Boost and Boost.Build.

No. I mentioned in some other post about why that's not a good idea.
