We really don't need one canon but heck I feel these new creators deserve to shoot from the hip and have a clean canvas to start on and not try to make everything done from the past work because it can not. I would rather have everything be in their separated entities TOS, TAS, TOS Movies, TNG and it's spinoffs, TNG Movies, DISCO, ST PICARD, but continuity is something that's still in and I don't like the connections which doesn't fit... so blow it up!!! Reset everything and start from one point, the JJmovies perhaps, and go from there, maybe there's something special with this new ST Picard series where it could cancel one universe and make DISCO the starting off point or merge them or establish there's multiple Star Trek universes ala TNG "Parallels" ex. where Worf traveled through multiple universes which spawned variant events of the Enterprise.
