Everything in core has to be built by every qgis package, and becomes a
required dependency, so "it would be useful" is not really the right
test.  It's more "It is so useful to many, on balance, that the overall
benefit outweighs the increase in size, compilation time, build
complexity, and dependency footprint".

I don't really have an opinion on the specifics of this.  It might help
to explain licensing, what the library depends on, build-time and
run-time requirements (anything not already required by qgis), whether
the library has a sane build system, etc.
