Capped deletes are the only remaining area where MongoDB performs untimestamped writes to replicated collections. This is a very complicated edge case for WiredTiger, and not doing it at all would give us increased confidence in the code while allowing WT to add more correctness assertions (WT-6838).
It is relatively simple to investigate whether we can perform capped deletes in the same WT transaction as inserts without doing all of the work in SERVER-16049.
