One thing that has happened is that most manufacturers have gone almost exclusively to "Tubeless ready" rims.

They have a center channel which you have to work the tire down into, somewhat like car tires.

But, invariably they are a pain to deal with. For those people who aren't planning to jump to tubeless, there is no reason to go with the tubeless rims. Of course, it is what it is.

For wheel removal, or not removing the wheel, perhaps some more techology.

Rubena Gaadi tubes.

Swap tubes without removing the wheel (you still need to get the tire off).
