I'm not the OP, but tbh the only thing that doesn't work for me is the apps that replace your input by the same thing in another layout.
For example, you have 2 keyboard layouts, type something and realize afterwards that you forgot to change the keyboard layout. You press the hotkey to trigger a script that removes your input, translates it into a different keyboard layout and pastes it back.
People who only use 1 keyboard layout don't even think about this issue and usually don't know such software exists.
I miss it a lot. There's 1 script that works in wayland but it's pretty buggy and it's not in arch repos, so I don't trust it too much. X11 had many options.

I get what you are saying and understand the balance between convenience and security, however most end users don't care. Their thing stops working and they complain "Wayland bad, my workflow now broken!", nothing you can do.
