Hi,
I think it's a rather nice idea :)

now, i want to think of a way to make something along the lines but that 
doesn't require any api change in old applications, which is necessary, as we 
promise long term cmpatibility and i don't want to have a kirigami3 for at 
least a couple of years.

an optional page stack on which is possible to push extra pagerows should be 
feasible, if applciationwindow.pagestack always points to the last pagerow, 
should be compatible and possible to achievable those stacked contexts.
