Ummm... that's not a bug.  It's a feature.  It think the point is that
you can use a combination of IK an standard hierarchial movement
togetheer, and not be stuck with one or the other.  After you move your
Goal, just select the top of the chain and hit Create Key (return), and
then hit "Selected Item And Desenants".  That'll make keys for them all.
And if you want to, you could parent you Goal to the top of the chain, so
when the goal is where you want you yous Create Key for Selected Item And
Desendants, and it's set.  Otherwise, how could you decidedly break the
IK chain -- say IK isn't doing what you want, of you some exact
positioning or something weird?  This way you have full control.  Once
you play with IK with Restrictions, you'll realise just how good it is.

It's an easy thing to program (making the key), but it's more powerful if
it doesn't.
