My personal best estimate is about 30% chance for the one such 
definition we have so far being web compatible.  But this is mostly 
based on gut feeling.

We have a proposal.  It's at https://github.com/domenic/window-proxy-spec

I have an implementation that I've been trying to land in Firefox for a 
few weeks.  I had to fix a bunch of our tests, then restrict the change 
to web pages because it breaks various extensions.  I'm pretty hopeful 
that I can at least get it to the point where I can try doing some web 
compat testing...

to follow along.
