The only concern I have with that is if someone paints themselves into a
corner and absolutely wants, say, LZO.
That would be hard to justify given that the kernel provides its own
decompressor code, making the compression format transparent to
bootloaders, etc. And no one should be poking into the compressed
zImage.
Some utterly weird things like the Xen domain builder do that, because
they have to. That is why we explicitly document that the payload is
ELF and how to access it in the bzImage spec.
Are you kidding?

And what format do they expect?

If people are doing weird things with formats we're about to remove then
it's their fault if they didn't make upstream developers aware of it.
And if the reason they didn't tell anyone is because it is too nasty for
public confession then they simply deserve to be broken and come up with
a more sustainable solution.
