Here I don't understand. Suppose Boost release X contains library A version
1.4, and library B version 1.23, and library A depends on library B. The
developer of library B then releases a new version (1.24), and the author of
library A doesn't. The next Boost release (Y) comes along, and now library A
is no longer part of the Boost release? That strikes me as a bad plan --- the
contents of Boost will vary from release to release as developers update their
libraries at different rates.

As an alternative, how about this: if library A depends on version xyz of
library B, then library B is pinned at version xyz for Boost releases until
library A is updated. If library A is not updated for n consecutive Boost
releases, library A is dropped from Boost as unmaintained.

How about this, also: a library developer can only release their library if it
is built against the latest released version of all its dependent
libraries. That way if a core library is updated, all other libraries will
have to use the new version before they can release.
