Hi Justin,

I think the risk of breakage is low: the previous extension mechanism
had only one use case, qemu-binfmt.  That use case is now gone, so we
should be fine.

I like this approach!

Together with update documentation and a changelog, it LGTM.  Could you
send an updated patch?

Thanks,
Ludo’.
