I think this should be used in addition to HTTPS. TLS is not the solution
to everything. In the WebPush scenario, using only HTTPS would lead to the
Push Service having access to, and being able to modify the content.
Content-enryption + HTTPS looks like a good general solution that can be
used independently of content-type.
