Here's the thing. Do-Not-Track was an active signal of intent from the user to the backend. Violation therefore, could be proven by merely showing the signal was sent, and the provider ultimately ignored it.
Getting rid of it for being "ignored" is ignoring that it is a means for the User to signal to the rest of us they do not wish to take part in tracking. Which in our world, is the important bit. A provider not being challenged with this bit can argue that the user doesn't mind being tracked because they didn't explicitly say so.

Mozilla is being a complete moron.
