 Description   

Server v6.0 is unable to generate change stream events for batched deletes, as SERVER-64972 is only available in 6.1. This can result in missing change stream events if the primary is on 6.1, and the change stream is open on a 6.0 secondary.

Fall back to legacy deletes for user deletes and TTL monitor when FCV < 6.1. This does not apply to the change stream pre-images collection, since that collection does not support a change stream against itself.
