Disabling Javascript isn't equivalent to installing an ad blocker. Ads not showing are just a side effect if it. If sites can't integrate ads on the server side it's not my problem. Same with analytics: you can still use regular web server logs. Everything beyond that is too invasive for my tastes.
Not quite. As lockers are common enough that they need to be considered. However, far less than 1% of users disable JavaScript (on the sites I work with). I'd be supporting IE6 again with those numbers, because the real cost is having to build and maintain the different versions of the site.
And all for what? Someone who isn't going to make us anything near the time it will take to develop.
I'm not saying what you want is wrong. Rather, what you are asking for is to have a game written in c to be rewritten in python because you don't want to use c applications.
