Initial testing suggests that it "just works". I'll add a small test, plus add a test for reads on views within a transaction, as all of those turn into aggregations like James mentioned.

We believe this may be no-op after SERVER-34094 completes

Comment by James Wahlin [ 15/Mar/18 ]

If we do not support aggregation in replica set transactions, we should ban find on views as well as they will be rewritten to an aggregation on the underlying collection.
