DNT is pretty much dead because no one ever really honored it.

Irrelevant information to the question.

Firefox right now has two options related to DNT:

"Send web sites a “Do Not Track” signal that you don’t want to be tracked

(_) Always

(_) Only when Firefox is set to block known trackers"

These two options don't become irrelevant, but the choice related to them does if the default is "block known trackers" (if that is the same as "block all 3rd party trackers by default).

And that is exactly why I would like it to not be forced on (or off). I want my browser to report no DNT setting at all, to reduce my fingerprinting profile.

https://panopticlick.eff.org/ reports that 1 in 1.67 browsers send the DNT header, so the best option fingerprinting-wise might be to leave it on, at least information-wise.

Of course, that ratio will likely change when Safari drops support for DNT entirely. See discussion here https://news.ycombinator.com/item?id=19101156

They send the header, but with which value? I probably didn't express myself well enough, I want my browser to send the "DNT not configured" value.

[rejberg]

Sorry, I left that part out. My browser sends DNT=1, and I get 1/1.67, which should mean that 1/1.67 browsers send DNT=1. This means that the total share of browsers that send the DNT header at all is at least 1/1.67, but probably higher.
