So which one do you want?
This question is silly. The handling of both is equal, only the command codes are different. So it's next to no effort to support both.
I've found a million posts on what the available options are and the drama that it caused, but nothing on what users actually want.
The users want that their file systems work with the driver, they don't care which technique is used internally. Some file systems use NSD, some use TD64. If you support both you make all users happy.
