Windows 8 logo devices already enable Secure Boot by default.

One aspect which makes all this really tricky is that Microsoft is
watching what we're doing and will keep raising the bar, probably not
with the intent to lock us out completely, but sufficiently high to
make things quite annoying. For example, any certificate-signing
certificate in the boot process needs to be an EV CA certificate,
which comes with fairly stringent requirements that are quite costly
to implement.

So any restrictions we implement as a good-will gesture will
eventually come back to haunt us.
