these are two different use cases. remember that a Containment has two primary 
purposes:

a) to contain a collection of plasmoids
b) to paint a background behind them

it is fully valid to want the same plasmoids on all your virtual desktops 
(using virtual desktops to organize your windows only) but different 
backgrounds. (b')

it's also valid to want the same background but different sets of widgets per 
desktop. (a')

it's also valid to want different backgrounds and different sets of widgets 
per desktop. (a'b')

i'm trying to find a way to offer b' right now in a way that works for 
composition managers (no other desktop wallpaper system do this properly 
right now, btw).

the neat thing is that the proposed solution also allows for a' and a'b' with 
a very small bit more work.

sure, so this is a sort of a'b' but with some containments appearing on more 
than one desktop ... and if someone wants different wallpapers?
