Or both, but obviously (b) first.

Such a library already exists in BSD, and need only be packaged for
Debian. In effect, (c) is just an implementation detail of (b) that
allows much of the porting effort to be shared among all the ported
packages. A person willing to put more work into a port might bypass
the compat library.
Actually, the BSD compat library even provides a degree of binary
compatibility, which we don't need. Much of it could be discarded.

Read the sources to the BSD compat library for such a list. I gather
that the NetBSD compat library interface is based on some old version
of Suse Linux.
