No way to create a new legacy animation clip anymore?

If I go to my project window, right click, and select Create > Animation, I get a new animation clip for the Animator component, not the Animation component. My whole game has been built with the legacy animation system. I have no skinned meshes, no "rig", no root bone on anything anywhere. As soon as I apply it, a warning message appears "The animation clip "Whatever" must be marked as legacy". Ok. So I open it in the inspector to check the "Legacy" checkbox. Oh great, there isn't a "Legacy" checkbox, and the attributes are all different. "Loop Time" and "Root Transform" stuff instead of just "Wrap Mode."

All you have to do to work around this is duplicate any existing animation clip made prior to version 4.3, empty it out, and use that for the new animation clip, so that's what I've been doing. But why is it like that?

Is it an oversight, or are they trying to kill off the legacy Animation component altogether and force everyone to use the new Animator for everything? It doesn't make sense to me for non-character animations.

Am I missing something? How do I create a new legacy animation clip in 4.3?
