Can we drop the allowed in non-secure contexts flag?

After Notifications loses it, are there any other powerful features that work in non-secure contexts?

Yes, I think we should be ok to drop it... Web Bluetooth references it, but to say that it doesn't use it.

Thanks - once we get the Notifications PR landed, I can send in a PR to Bluetooth to remove the reference.
