Some utterly weird things like the Xen domain builder do that, because

Are you kidding?

And what format do they expect?
I think they can be fairly flexible. Obviously gzip is always
supported. I don't know the details.

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.
Well, it is too nasty for public confession, but it's called
"paravirtualization".
The fact that you are aware of it means we're not going to break them.

But my point is that we must not be held back just in case someone out
there might have painted himself in a corner without telling anyone.
