It's not explicitly allowed but in my awareness it's not forbidden either.
Since it is an implementation detail it would appear to be outside the
scope of the standard.
In response to the second question, it is not necessary to support a
negotiated offset of one. In the extremely unlikely event we received such
a negotiation response from the target then we can negotiate a mode other
than DT. This is an option any time you receive a negotiation message for
values you do not support.

I don't see these words anywhere in the current spec. Can you give me the
source of your interpretation?
