Don't quite understand this change (sorry, probably just being obtuse).

The signature was changed to make sure older kernels don't handle
compressed images by accident, right? If so, this would seem like a bad
idea, because this is what can actually happen now.

Shouldn't user space learn how to handle both signatures instead?
