The main reason I could imagine is security.

Right now with X11, IIRC, if one application has access to your display they can read what is going on in other applications running on the same display.

If browser tabs were able to do that, all hell would break loose. So why do we accept it from applications?

Anyway, despite this, I still use X11 instead of Wayland because of all the shortcomings.

Because I don't run random untrusted apps all the time. Whereas I do visit random untrusted websites all the time.

		But Snap and Flatpak have an advanced permission system, designed so you _can_ run random applications that you don't trust.
