My gut feeling is that Discovery (and "Calypso") will be retconned out of existence if it comes down to it for any future installment if this ending gets in the way.Imagine if Turnabout Intruder ended with Admiral Kirk happily married to Janice Rand, with a kid, sending the Enterprise off on some bizarre mission where it needs to wait in space for 1,000 years. We'd start running into problems as soon as Star Trek 2 (or even TMP).
That any future post-Kurtzman regime that might want to go in a different direction will "reinterpret" the material in the same way that Goldsman and company have done to the original IP.
