Yes, interesting indeed.

I remember I once listened to a presentation by David Andrich who
proposed a Rasch model (so, no a parameter) that takes guessing into
account. The fancy thing was that the degree to which the response was
governed by guessing was modeled as a function of beta (b) and delta
(D). Leads to very strange ICCs but makes a lot of sense.
