A couple of packages you may be interested in

[chanced]

• https://github.com/chanced/caps is a unicode case conversion package that support idiomatic acronym casing. It is stable and feature complete.
• https://github.com/chanced/openapi may be a decent starting point for 3.1 if you decide to support it in the future. It may need additional work.

I sort of moved on from go and hate that these are mostly sitting unused. Perhaps ya'll can find some use for them.
