One possible solution to this is to make the activity window undecorated (we do not need maximise/minimize/resize buttons), and making their height/width equal to the dimensions of the screen.

Maximize + undecorated might work. It has to be done by each activity.
The only alternative I can think about is to add an option to metacity
to make all toplevel windows undecorated and fullscreen. That would
not play nicely with stuff like the GIMP or even simple/small
applications like GNOME calculator.

Yep, latest metacity has a CM I think.
