The DCP has grown to become a giant staple of the WDW labor force due to the weird dynamic of the Central Florida labor force. Disney is full of a bunch of service roles that aren't really conducive to career building, really making it to where, once the best candidates were combed through, Disney was left to fill a lot of their roles with local teenagers/young adults and retirees. Both of these groups aren't exactly the most consistent, which is why Disney, after having their small version of the CP start in the late 70's, eventually grew the program into the behemoth it is today, so they could always have high availability of labor without relying on locals. The DCP is effectively why it's so rare to see Orlando high schoolers working at WDW as anything other than a lifeguard (which is comedically different to Universal and SeaWorld).
Now, the need for labor is greatly reduced, so by taking out the DCP, many more jobs will be spared than what would have been the case. (I highly doubt the next part will be the case, but as a hypothetical) if Disney managed to run through all of its backstaffing of FT, PT, and Seasonal, I'd expect we see a small resurgence of local hires before the DCP is restarted. Why? Because the DCP has grown into a machine with such intense marketing, that it is designed to produce a crazy number of applicants with a crazy number of hires. And I doubt Disney would want the publicity of the DCP getting ridiculously competitive.
