The simple and straightforward solution is to leave the rpm API into 
librpmio, and use a separate one for the PGP backend. Ie the backend 
implements an API which librpmio calls, and therefore we have the right 
dependencies automatically.

That's how the crypto backend between openssl and gnutls works, and 
ditto with rpmdb backend. Runtime swappable can be handy for testing, 
but maybe not worth here.
