Currently, the change_streams_per_shard_cursor_passthrough suite excludes the tags:

- assumes_write_concern_unchanged 
- assumes_against_mongod_not_mongos 
- assumes_unsharded_collection 

These tags are excluded primarily because the change_streams_sharded_collections_passthrough suite, which the per_shard_cursor suite was modeled after, excludes them, and because we want to ensure that any test failures in the per_shard_cursor suite that don't exist in the sharded_collections suite are introduced by per shard cursor work.

However, after per shard cursors are implemented and initial differences are investigated, we should audit these tags and see if they make sense for the purpose of the per_shard_cursor test suite, and potentially expand test coverage.
