Btw, I suspect either of these are reasonable. In fact, I don't think
it would be at all wrong to have the desktop launcher have an option
to "launch in a group" (although I think it would need to be named
better than that). Right now, when you create desktop launchers under
at least gnome, it allows you to specify a "type" for the application
("Application" or "Application in Terminal"), and maybe there could be
a "CPU-bound application" choice that would set it in a CPU group of
its own. Or whatever.

So I do _not_ believe that the autogroup feature should necessarily
mean that you cannot do other grouping decisions too. I just do think
that the whole notion of "it got started from a tty" is actually a
very useful thing for legacy applications, and one where it's just
simpler to do it in the kernel than build up any extra infrastructure
for it.

So it's not necessarily at all an "either-or" thing.
