Ah... but that's the rub, isn't it? An Empty has no notion of what
"pose mode" means. As far as what the other packages have done and can
do, who knows how that's implemented? From userland it may look like
you're adding a regular empty to the Armature hierarchy... but under
the hood it may just be a bone drawn to look like an empty. The user
just isn't told the difference.

Now, if this is the route you want to go, have a go and try. It'll
probably work fine since the changes are largely cosmetic. If you're
pushing Objects to bone-level, though... you may want to wait until the
animation system in 2.5 is fleshed out.

But... I'm no authority.
