JL> That seems strange,

It is the impression I've gotten from reading the various project lists.

If I got it correct, some hardware devs recently complained about that,
too.  Something about having to send the data through the hw twice if
the hashing is part of eddsa rather than separate to it.  So protocols
seem to want to ignore the pre-hashed versions, too.  The feedback
between the two is likely a factor.
