What we need is a decoupling of the keyboard/mouse events and common shared application functionality.

In my opinion apps should offer an API for cut/copy/paste and the DE maps it to concrete events like Ctrl-C. This would make it easy for people that switch between Mac and Linux to have copy on Super-C and keep Ctrl-C for cancel in the terminal.

Just as a single data point: I use middle mouse paste maybe 90% of the time. The only inconvenience is that you can't select and copy, then select some other text and replace it with what you copied. Oh, and I've been using Wayland full-time for more than 4 years.
