They're *potentially* useful.  Analogously, I allow color-stops before
0% on a radial gradient, even though they're not displayed - the
colors are still interpolated, so you can actually start the gradient
part-way through a color transition.

However, it seems much harder to come up with decent reasons to want
this functionality in keyframes, so I'd be okay with just dropping
them.
