Yeah. I already complained that the device independence is in the
wrong place (in the client rather than in the server where it belongs).
I forgot to add that device control is in the wrong place as well.

With Blits and NeWS, you can download code to handle certain events
locally.

But what's worse than sluggish response is the indeterminence
of type-ahead and mouse-ahead operations. There is no guarantee
that a client won't open a window right where you're typing
or mousing and steal your input. With local device control,
these operations can be synchronized.

This was one of the motivations for Mark Weiser's pie menus. Even
if the windowing system is slow, you can click a button, move in
a certain direction (say, northwest) and release, even before the
menu is drawn.
