[Ach] Proposing RSA keylengths

I consider Moore's law to be in favour of our recommendations. Some performance problems fix themselves over time.
So if you're running on 2048bit RSA you're likely ok, we recommend to opt for 4096bit RSA on new deployments if possible.

I second the use of RFC like wording (and propose to also include the introductory pamphlet on how to properly read these).
