You can't really reboot Star Trek without mass hysteria.
Well, you can. Like the Abrams films, that mass hysteria comes from a small corner of the interwebs. The Discovery folks are going to pick and choose what works, and ignore what doesn't (they aren't going to keep anti-matter blowing up the universe from "The Alternative Factor"). Along with the visual redesign, it pretty much says reboot to me.
Everyone's mileage will vary.
