These strategies usually come to the FPC in the context of bundled libraries
but they're actually static linking examples.  In general, the FPC considers
bundled libraries to be very problematic, static linking (and their analogs,
like packaging a library's source and then having a dependent package
compile against that) to be somewhat problematic, and shared libraries to be
preferred.

When there is "no reason" (the FPC is often called upon to evaluate whether
a valid reason exists) not to take the preferred strategy, packages need to
be modified to take that route.  If the FPC finds a valid reason for that
not to work, then the static linking alternatives are looked at and finally
the bundling alternatives.
