I don't know about 'great deal' - but I do see value in it being an
optional way to run your identd.

I think it comes down to this - who should have the responsibility for
maintaining the information?

If MY identd hands you a token which is all the information I will need
back from you if you file a complaint, then I'm no longer responsible
for maintaining my logs such that I can keep or throw them away without
regard to this particular use of them.

if MY identd hands you a timestamp, I'm now required to keep those logs
for a(n unknown) period of time.

The encrypted reply option would seem to solve the problem more completely.
(Except for regions with prohibition.)
