[Bf-funboard] Empties in the bone hierarchy

When you are working in a pro studio enviroment, time is money so any time
you save is time to meet your deadline and less money squandered on paid but
lost manhours.So, most pro rig rig controls use simple controls (boxes,
circles,crosses,spheres). Secondly, non armature controls makes the rig
"cleaner" for the animator to be able pose effectively.The less you have to
"hide"on a rig represents less package computation thus faster graphical
response.In Blender, you have to designate which shape you would like the
bone to take by calling forth an object, cause the bone to draw the object
(which has to already exist somewhere in your .blend file) and hide the
object that the bone is going to look like (that has to exist but is doing
nothing but existing)and use the bone that looks tlike the original object
Imagine 6 characters with complex rigs with bones that look like something
they're representing with the original objects just "exisiting" in the
.blend file when all that had to be done is to be able to use the original
object anyway.You have objects in your files doing nothing but they have to
be there "hiding" because if they didn't exist you would have no icons
because the bones would have nothing to "look like".
Other packages don't have pose mode either.So there are no objects that
can't be used in their versions of the action editor.Try using the action
editor and try to adjust timing with an empty or non bone in concert with
your rig (using bones)in pose mode.You simply can't because it's not an
intergrated part of your rig.So, now you have to use workarounds that take
more time.That's why you need bone heirarchy with objects in Blender.
If you're a hobbyist, you have all day to do these things.If you make your
money by rigging and animating, and have to meet deadlines, every step saved
is a plus.The less you have to "hide" on a rig, is less you have to remember
to keep track of and in a pro setting, the less the animator has to tamper
with to break your rigs.
Just my two cents.

I'm still confused why you'd want to do this at all. We don't support
the concept of character sets, so it doesn't make as much sense to
have non-armature controls. You can mix bones and non-bones just fine
(situations the parenting system doesn't support, constraints do), but
generally non-armature helper objects are used behind the scenes,
controlled by bones. Also, empties as controls wouldn't have a rest
state, the way armature bones do.
I don't see how this adds any power at all. . .abstractly, a bone is
simply an empty with length. Getting rid of the length isn't going to
help you any.

You realize modeling icons for a rig only takes up a very, *very*
small percentage of the time? Why would this "take Blender's rigs to
another level"? What power does this add? Modeling icons simply isn't
a time-sucking activity for riggers. Besides, different people have
different tastes in rig controls. I myself prefer very visually
minimalistic controls, while others prefer more prominent ones.
A better solution is probably to have an option to put an empty shape
on an armature bone directly. Using empties simply for their shapes
is a bad solution, I think.
