Gary, listen... I respect and thank you for all of what you've done to make 
gpsd amazing, but you can't be right all of the time. In this instance, I know 
that you are breaking gpsd and your justifications are really insufficient and 
I'm obviously not getting the point across. Could you please get this change 
reviewed by someone else, like maybe Eric?

Thank you.
