We got a lot of noise from validation failures due entirely to "Use of deprecated BSON binary data". This is noisy because validate fails and says to look at the logs for log id 6825900, but this warning can generate millions of log lines and make it difficult to find other issues.

Validate should not emit errors for deprecated BSON (or similar issues) - they should be warnings. Importantly this should not hide actual corruption issues that use log id 6825900
