I don't mind as long as it's callable from other languages (either
using generated bindings like GIR or using hand written bindings).

I would just caution that I found GIR was not expressive enough to
implement libguestfs bindings.  Specifically it lacked support for
optional arguments and structs (unless encapsulated as an object).  I
don't know whether or not that would affect zif.

libguestfs lets you edit virtual machines.  Supports shell scripting,
bindings from many languages.
