Exactly. PKCS#11 exports exactly one function from a PKCS#11 module:
C_FunctionGetList. So in this sense the ABI for a PKCS#11 module never
really change in a backward incompatible way.

The remaining methods exported from that function should be accessed
through libp11-kit.so.x.x.x directly. The fact that its a both a library
and a PKCS#11 module allows us to handle the initialization refcounting
issues elegantly [1], but callers should generally treat it (and link to
it) as one or another.
