z-index is animatable because why not?  It's a number, and numbers can
be transitioned.  I agree that there's not a lot of use, but given how
simple it is once you support animating other numeric properties,
there's no reason to shut it down.

I will suggest that you probably don't actually want to transition all
properties.  It's rarely a good idea.
