IMO, MDI is a specific implementation of an "overlapping windows" implementation. In some scenarios (like AIR apps) the true MDI windows (equivalent to other top-level windows of other apps) was the AIR NativeWindow itself and no ActionScript code managed how those MDI windows behaved.
But even if you try to simulate MDI within a browser window, each MDI window might itself have a stack of popups and z-order and focus/activation have to be managed within that window. So there are lots of possible PAYG implementations, IMO. It shouldn't take much code to just handle someone's "Find" dialog, but it was a fair amount of code to do what Flex did and divide SystemManager into normal, popup, tooltip, and cursor layers. This will probably be DAYG (Do As You Go). We'll figure out some implementation when someone actually needs it.

And in Flex we had external MDI library to do that. For me that's a concrete case and people that wants to do MDI should start that effort and make a new library. So IMO we should start to that need to invest time in this. Regarding zindexes, in Jewel I put things on some concrete index but I as well thinked that I should define a range, but still didn't. For now seems not urgent, but I remember in Flex at some point was needed (and was in that MDI app we did).
