That's not worse, that's different. The positive side is that applications can't silently snoop around keylogging the system, transparently capturing things or using XTEST to bypass authorization.

Worse would be if you couldn't do it. On the contrary Wayland gives users more control over their machine than previously at least in principle (and application developers lose some control, which is obviously where a lot of frustration comes from.)

X11 is mainly deprecated because nobody is really willing to work on it. The one person who wanted to work on X.org kept breaking shit. None of the desktops want to, or even can afford to, maintain X.org and Wayland paths forever. If people are upset they can get a full refund, at least.
