People can host their own competitions with different rules, and do: Red Bull has their own format of competitions where inspection time is not included. However, under the regulations outlined by the World Cube Association, inspection time is required (except in blindfolded formats).

If there’s sufficient demand, the World Cube Organization could (and probably should) organize two events, or one event with two championships.

You see that in many other sports. Basketball has 3×3 championships, road cycling had the road race and the individual time trial, cricket has at least 3 different game formats (tests, one-day, and T20), soccer has indoor and outdoor forms, sailing has many different boat types, swimming has separate events for 25m and 50m pools and for open water swimming, etc.

The WCA already does have multiple events for different puzzles and styles of solving, such as 7x7 cubes and solving a 3x3 with the fewest moves. All but the biggest competitions choose from a subset of those 17 events to include because there's too much demand. There's no technical reason why no-inspection can't be an event, too. No-inspection was an event for 6 months over 15 years ago, but I can't find any information on why it was removed. That being said, it's still possible for a event organizer to have an unofficial event as part of the WCA sanctioned competition. I've recently been seeing Face Turning Octahedron appear as unofficial competition events.

Wow I had no idea about the no inspection event, was it with the WCA?

Yes, see article G: https://www.worldcubeassociation.org/regulations/history/fil...

4 if you include The Hundred[1] (although I don't think it's been exported out of England yet...)
