As a user of the SCS schema registry and as part of the schema registration and validation process, I need to be able to know if a schema being registered is compatible or not with pre-existing ones to make sure we are properly evolving schemas.

I believe this already happens. I'am using Confluent's Schema Registry and normally when registering an incompatible schema the server returns a response code 409 (CONFLICT).

Extract from a stack trace exemplifying that: Caused by: org.springframework.web.client.HttpClientErrorException$Conflict: 409 Conflict: \"{\"error_code\":409,\"message\":\"Schema being registered is incompatible with an earlier schema for subject \\\"test-subject\\\"\"}
