This is a technical working group not one for speculation. If two chains emerge the weaker one MUST protect itself. We will know the weaker chain almost instantly when block 494,784 is passed. Until block 494,784 this is a non-issue.

Without strong native two way replay protection at the protocol level, the responsibility will fall upon every wallet and service provider. As a result I'd expect to see a longer period of disruption / inaccessibility than we saw with the BCH fork, and probably several orders of magnitude greater instances of nontechnical users making mistakes to their own detriment.
