I think, the distinction between 'boost.core' and 'boost.optional'
(or 'dependent' or sth.) could also be useful to release the strong
requirements concerning dependencies between boost libs. While core
could still be (almost) free of lib interdependencies, 'optional' libs
could freely link to others (possibly even third party, i.e. XML
parsers etc.). IIRC, property tree was critisised because of its
dependencies, but when libs get more complex (and more directly
related to applications), such dependencies may be inevitable and even
useful, while it's still nice to have a core of independent libs.

Sounds like a lot of work for the maintainers and the release managers.
Maybe it would be sufficient to let every lib have ist own version (aside
from the boost version) and use the usual versioning scheme, where
changes of the minor version denote downward compatible APIs while new
majors indicate API breakage (versionwise).

Just my 0.02EUR as a lurker.
