No it isn't.  The cost is 64-bytes *and* user confusion with two
completely different "headers" for no reason what so ever.

Why use the ARM64 version and then have it *block* existing boot
loaders which look for the zImage magic from being able to boot an
Image.

It's a much saner idea to use the ARM32 zImage header than to use the
ARM64 version - or nothing at all.
