There is also a big problem of binary incompatibility between different
versions of ghc, and dependence on the exact version of modules our
package depends on.

Dynamic libraries work for C because C has a very stable ABI. Also
it's easy to maintain binary compatibility in libraries. I'm afraid
that cross-module optimizations of ghc make dynamic libraries nearly
impractical.
