Then it should be documented, because currently, task-* is polluted.
Since everybody add his pet peeves packages as task-*, that cause the
same problem that was intended to solve, ie too much choice. People have
the warm fuzzy feeling of having a selected and taylored set of rpm, but
that's far from the truth.
Also, it abuses suggests and interact in a weird way with auto-orphans
( or it should be better to say that it make it dangerous for users to
use the feature, thanks to the lack of semantics for Suggests, coupled
with lack of clear semantics on task-* and the abuse of the 2nd one by
the first one coupled with a too simple UI ).

So basically, that's duplication of information ?

</I>
Suggests semantics are still unclear. For now, that's "let me use this
to push totally unrelated packages in the default setup because I think
they should be installed but I have no way to explain why, and they are
important but not important enough to be documented or selected at
runtime". And that's far from being ideal.
In fact, the more I can think of, the more I wonder what was the problem
we wanted to solve with Suggests, and if we really did. The UI is near 0
and will be for a long time, since there isn't enough expressiveness in
a rpm tag for that. Advanced users, who are concerned with deps and what
is installed either remove suggests ( my case, because it pull lots of
unneeded stuff ), or just do without it for finding related packages
( because you still need to look on why something is pulled, and you
cannot really select ( not that asking a 100 questions would be good
OTOH )).
Less advanced users do not care at all about suggests in the best case
( ie, it solved almost nothing for them ), and end with auto-orphans
doing weird stuff. It also have a weird interaction model on upgrade
( like "if task-kde4 is installed, do I want to also pull all suggests,
even those I removed, or do I want to not do it, and then end with a
different result than from a fresh installation" )
So I would suggests ( no pun intended ) to just drop them. Keeping them
make us diverge from upstream, afaik, requires various hack with some
side effect and extra documentation for almost nothing ( ie, since we
may not have solved a real problem ), and think to do think another way.
