I can't really speak for Street Fighter V, but I can say that Easel would assign command delay to the person who is introducing it. So if a person is somehow forcing their inputs to arrive later than they should, they would be assigned more input latency so that the other players would be unaffected. Easel also has a lag spike protection system where the server will just forcibly reschedule inputs if they arrive really late for some reason.
