Star trek writers only rarely let themselves be tied by canon anyway; they use what they want and ignore or contradict the rest as needed/wanted. Gorn are a good example: SNW turned them into "Aliens" from another franchise, but TOS also remains canon. How often have the klingons been redesigned? Jadzia's Trill is not a tng Trill, and so on.
I doubt there is a much inclination anyway to use Prodigy properties in live action. The SNW guys would be the exception, but they have already done a crossover and probably aren't going to repeat that.
We don't know that, they could still opt for the tax break if they don't get a relatively decent offer from another streamer. The good sales of physical media boxes and other related merchandise makes that less likely, but if netflix and co don't bite, it may still be over.
It would have remained canon, however. Nor would it be functionally deleted, those bluray discs (and the books and game) don't cease to exist (and neither should digital purchases, allthough that may depend on the platform and how much those are willing to rip off their customers).
