@ro Eh, if it's geared towards your personal use-case anyways, I'd say just don't package and release it as a… crate I think is the term in rust?
If you wanna be super clear about this, you can just add a README with a note about what use case it actually works in or it not being for public consumption or whatever.
That way people can find it and use your code to possibly find a solution to their specific problems but it's clear that it's not a supported package.
