I wonder if people use the 'blocking' variant.

[gklijs]

I think for the future of this crate,it would be good to split it into multiple crates. Part of the sub crates will be a schema registry cliënt.

The base should/could be created based on the open api spec available. I'm considering doing so in a version 4 release, as there likely are breaking changes. The whole crate would be a lot simpler if I only conciser async. However, I can't see which features are enabled when this crate is used. Therefore, please let me know if the blocking variant should stay.
