You're assuming that all backends must be built as part of the quince tree.
What if I wanted to write a backend private to a particular application
and never intended to be published (perhaps it's some proprietary data
format rather than a "real" database)?
If the core were always built, it could be used with a custom backend
that quince's jam file knows nothing about. (Provided that the core
itself doesn't have to be modified to add a new backend -- but I would
hope that's true as it's part of standard coding principles.)

All of sqlite or just a connector to it? I don't have any particular
opinion on this either way, but bear in mind that if you do the former,
users may still wish to use a different version of it (perhaps they need
a bugfix from a newer version than shipped with quince), and (especially
if you don't provide a way to do that) users will expect you to keep it
up to date, which increases maintenance costs slightly.
