It does yes, but it's not the only thing that does, it's sufficient
for a client program to request input focus and get it, and when
running fullscreen windows I'm not too bothered about which one of
them has focus so long as it's the topmost one. (And as these are all
fullscreen apps that don't make any effort to release focus that's
always the case.)

Surely It's entirely deterministic? I start mythfrontend, it opens a
full screen window, I start mythwelcome, it opens a full screen window
ontop of mythfrontend (the x server doesn't arbiterially decide the
stacking order, the last opened window get opened on top.), I start
XBMC, it does the same again.

I quit XBMC and focus returns to the last window that has it, ie, mythfrontend.

I quit frontend and the same happens with mythwelcome.

It just seems pointless to waste time installing and configuring
something I don't have to, for no discernable benefit. (PS, surely
those mem values are 4K and 28K respectivly. ;) )

Don't misunderstand me, running a window manager is probably 'a good
idea' for most people. However there's no real problem not using one,
you won't do any harm. (At the end of the day, it's a TV playing box,
if it gets confused I ssh in an pkill X.)
