   You're right. I think we should disable WAP with RTAS until we figure out what the behavior should be.

   That's right, but it is an example of not being able to simply use the list of snapshots. This was a side point that supports the idea that point in time lookup should be done using the snapshot log, or metadata file log if it is not available, and snapshot lookup should be done strictly by id.
