With which preferences set?  (It sounds to me like you wanted
show-windows-from-all-workspaces + restore-to-native-workspace, which
is one of the cases we happened to cover, but maybe you had something
else in mind)

It actually seems to be a much nastier issue, with people wanting all
kinds of weird choices.  Here's someone who tried to summarize some of
the different possible modes and part of why people might want certain
ways or another:  http://bugzilla.gnome.org/show_bug.cgi?id=81222#c19.
 Do you have any similar bug(s) in kde bugzilla?  I really don't feel
like I understand all the ways the taskbar is used with the reasons
for why people use it that way (I use virtual desktops constantly but
I personally don't feel any need to have the taskbar show windows from
any other workspace than the current one.  *shrug*)

Yeah, I like 0 being separate.

I'm worried that if we define it in terms of behavior then instead of
just having pagers use it we'll have apps start using it just to be
different and causing inconsistencies.

I'd like to have both a 2 and a 3, actually.  If we think of the
wording for 1 as
  1 - "a request from an application to activate the given window"
then the definition for 2 and 3 would be something like the following:
  2 - "a request from a pager which has workspace/viewport-aware UI to
      activate a given window"
  3 - "a request from a pager which does not have workspace/viewport-aware UI
      to activate a given window"
The reason why I'd like a 2 and a 3 for this just goes back to the
rationale we have for _NET_ACTIVE_WINDOW[1] and trying to be able to
determine whether we can infer that the user made a request about all
the other windows on the current workspace and
window-to-be-activated's workspace.

Of course, WMs would be free to treat all three request types the same
way or have different policies for each.  (In particular, I might like
to make 2 and 3 different from 1 in regards to show desktop mode, as
well as having 2 different from 3 in regards to workspace switching)
