I love this improvement, but I would like to coordinate this with an App-wide OpenAPI spec, and App-wide media validators (we would support both ways, just as middleware and hooks coexist).

Unfortunately we won't be able to complete all this before the 4.0 release. Let's circle back on this for 4.1.

hey! jsonschema-rs author here. Please, if there is anything missing on the jsonschema-rs side, feel free to tag me, I'll do my best to improve the lib and make it more suitable for your use case :)

hi @Stranger6667 thanks for the offer!

Off the top of my head I don't think there were particular problems with the lib, but I will mention something if anything comes up.

Thanks for reaching out @Stranger6667!
Echoing @CaselIT, I don't think this is blocking on jsonschema-rs in any way. I'm yet to take a look at this PR more in depth, it unfortunately got sidelined because of the 4.0.0 release work.
