The NYC network is so resilient that all damage caused by flawed 1.3 code will immediately work itself out. My missing unconfirmed sends hanging on Coinomi for 3-4 days will now magically confirm. The NYC network is time-tested and proven!

Upon extensive, lengthy beta-testing AND UNDER THOSE CONDITIONS ONLY should a fork be considered. 2Q/3Q 2019? I guess it depends when we have fully working codebase. Then we will need lengthy testing and review. And finally implementation.
