These kind of flags I'm not sure will buy us anything. They're not
likely to change ever, so we're just forcing new platforms to add more
and more boilerplate to the feature structs/templates.
While I generally disklike negative flags, I'm almost tempted to say
that for stuff like this, it might be better. That is if we even want to
turn them into flags.
