I really believe passive grabs can be replaced by adding an API that 
says "I did not handle this event". It can then be passed to another 
window. The typical grabber would be the *last* one in line, not the 
first. Wayland itself would have simple unchangable rules about what 
windows receive events, but these rules produce a list and it tries each 
in turn.

Grabs have the unfortunate problem that the grabber cannot change it's 
mind, and grabs must always be obscure key combinations and sequences to 
avoid the chance that they will interfere with some program.

I would really love it if "all clicks the program ignored dragged the 
window" and things like that.

I can think of a million obvious problems with this but I don't think 
they are insurmountable. It would seem more in keeping with Wayland's 
design of being minimal. Wanted to know if anything like this is being 
considered?
