And if there is not enough time for the new prime to be generated, it falls back to the old one? I agree that manufacturers should be using a different prime per, at least, batch of products.
My fear would be device makers getting it horribly wrong on the devices in question. E.g.: http://www.theregister.co.uk/2015/10/21/german_govt_mulls_security_tests_of_sohopeless_routers/ Having a large pool of known good primes would be easier for them to use I suspect. Sadly we can't let perfect be the enemy of the good, or in this case the "not completely terrible".
