The difference is that there is a communication channel. In your second 
case, if a UA has implemented the API, the service can issue a call 
whether it has an exception, can try to store, test again => still no 
exception, clear that the user doesn't want this => react accordingly. 

in the first case, the thing will just stubbornly spawn meaningless 
DNT:1 headers. Again, feedback mechanism, the service may decide to 
ignore this guy's DNT:1 and send a "D" for "Discarded". Your full 
implementation knows what's happening, the DNT:1 spawning 30-liner on 
your router won't. The user will lose out here. 

It burns down whether we want a communication tool or a stick to bang on 
services. I know that the browser makers have limited resources and this 
is not the money-making sweet spot. But implementing DNT hopefully gets 
some unrest out of the market. For that to happen, IMHO, we need a 
communication tool and not just a DNT:1 stick. If browsers don't 
implement their side of the communications tool, why should the services 
take the burden to implement the other side? => arms race again...
