In one hand, yes, simpler and probably less data. In the other hand, WAY less flexible. The piece of program can easily discard torque data and i.e. read some sensor built into the cartridge, or apply completely different algorithm if it's some special cartridge i.e. for printing with plastic - anything the authors of the printer firmware did NOT foresee at the time of creating the printer firmware, methods that can't be covered by plain change of the parameters because they weren't known at the time when the algorithm taking these parameters was written.
(and as Lexmark lost the case in court, obviously if they included that feature strictly for law reasons, it didn't work.)
