Looking at some usage in Spring Kafka, it would be nice if the suppressed exceptions that are added in the RetryException would be a bit more visible.
We're considering adding a callback where a user would get the RetryException and run some recovery logic based on what happens. The number of retries is of interest. I am not sure that being able to inspect the inspections is that useful, but it would certainly help if we had something higher level than the suppressed exceptions.
