Wearing, as usual, my receiver hat, I still don't see any reason to be
interested in random senders' opinions about the relative merits of
various algorithms.

Like I said before, let's say someone publishes SSP saying sha256 is
deprecated and rot13 is shiny and new.  What should I do with that info?

Assuming we agree that it's stupid and I should ignore it, how am I
supposed to tell stupid deprecation advice from non-stupid deprecation
advice?
