At the bottom of the page:

    WARNING:
    DO NOT USE BEACON GENERATED
    VALUES AS SECRET
    CRYPTOGRAPHIC KEYS.

Can you point to where exactly do they advocate what you say?

I said "security", not "as secret cryptographic keys".

Am I the only one who read the entire page? There are three links prominently featured on the page under the "Uses" header:
