No problem. This is a per-nickname identifier. Use temporary disposable /
throwaway accounts or context specific accounts if you wish. Then you won't
have everything linked to the same account.

The type of tech Mozilla Personas (or U2F) was using to anonymize the
original account you connected with can be reused, although that would
break the universal addressing aspect.

Or how about this - you can link multiple profiles / personas / nicknames
to your account, including creating throwaways, and get to chose which one
to link third party services too when you register with them.
