This ought to be doable without too much trouble for minor releases.

Since most of Boost's libraries are header-only, that's meaningless for
them. Mostly, anyway.
ABI compatibility is to be maintained by the compiled libraries
foremost, they would have to worry about this the most. It can be done
with a bit of understanding of the issues and some discipline.
The question is, is it worth it? Any application that uses a precompiled
Boost component probably uses other Boost components, too. As such, the
likelihood is high that upgrading Boost means recompiling the
application. Thus, keeping the ABI is kind of pointless.
