That was not at all the primary motivation for including tkr information
in the descriptor. The reason was to give vendors enough information to
create valid dope vectors. Not just one vendor, but all the vendors.
This is a basic implementation and performance issue. To say that the
TKR information is "useless" without these other features is just nonsense.
