Nah, 90% either don't or wouldn't use them if they were there.
Sure, if you ask people directly if they want more options, they'll say yes, who doesn't want more choices? But that's a different thing from actually using them when they're available. The vast majority of users for a utility service like a search engine just go with the defaults.
Well, a year after we implemented 2FA, I queried the database for users with 2FA enabled, 3 people had it enabled.
Aside, only somewhat related to the previous story, the idea that users want a bunch of knobs and levers is just an example of the HN delusion where HNers regularly think they represent the population, like the person using the Lynx browser.
The first few times I saw it, I thought they must have been joking or trolling.
I don't even have time and budget to make my site work well on older versions of IE. It would be insanity to optimize for the 12 people that use lynx.
Even Facebook used to work with Elinks (don't know if that's still true).
Don't let your supposed experience as a professional techie give you the false impression that you know everything there is to know about tech.
First day in my Intro CS class at college, a dude asks about whether the class website supports Lynx.
