​I would phrase it differently. We will use DKIM until we start using
something different to SMTP.​ I can't see a viable transition path out of
DKIM without re-designing SMTP.

The only thing I see on the horizon that might force us away from ed25529
is quantum and that is going to be so different that backwards
compatibility just isn't going to be a concern.
