I am fine with that choice.

There is also the suggestion to make AES-nnn mandatory and 3DES optional
when used with v5 keys.  I would be in favor of that; I don't care on
whether this is AES-128 or AES-256.

We can only do that when used with v5 keys.  We can't do that in



Die Gedanken sind frei.  Ausnahmen regelt ein Bundesgesetz.
