Well, by standard, I'm supposed to start out negotiation with the fastest I can possibly do and the drive modifies this in its reply. The heuristics over DT vs non-DT in the transport class are to cope with arguably buggy drives in the field. I've never come across a DT capable drive on an LVD bus that showed a problem in this regard ... have you found one?
