I still believe that the ironic-lib project was designed to share code
between the Ironic projects _only_. Otherwise, if it the code was
supposed to be shared across multiple projects we should have put it
in oslo instead.

The governance description is a bit vague [0], it does say: "A python
library of common ironic utilities.". Does it include out-of-tree
ironic-related code? I would like to think that it does not. The fact
that ( IIRC ) we never stated that this is a public library, there's
no documentation of any methods/modules there, no release notes, no
sample usages, etc... Makes it a bit unsuitable for 3rd party

That said, I'm not totally against make this library suitable for a
broader usage but this will require more thoughts on it and effort.
