And cloudflare, akamai, and hcaptcha lock you out of 80% of the Web.

Nope. YouTube, for example, works like a charm. Settings allow users to select a user agent or set a custom one.

Given TFA, I have to assume you are bragging about being the most fingerprintable user on the Web.

Correct, sticking out is not the best approach. The only protection users of any modern browser have (while still having usable APIs) is whitelisting which sites can request information like enumerating system fonts and serving every other site fake/random information, likely through addons. Say a fingerprinting mechanism wants to enumerate your system fonts, you look up your whitelist, and if it is not on it, browser serves it the most generic list (can be gathered from fingerprinting datasets like EFFs) or finetuning it until your score is as generic as possible. Essentially, blending in with the crowd. Having such whitelists would make browsing a bad visual experience, but hey, why not do what we can to make fingerprinting as difficult as it can be. I don't mind having this as a native feature which prompts the user as they browse, sample prompt: "this site would like to access the following information about your browser, will you allow it or serve it generic, the least fingerprintable set?".

Are there add-ons which do this?

Once this feature becomes common, sites will fingerprint using the delay from the user to click the permission in the dialog.

Really. This whole field is the devil’s work.

Basically we need something like NoScript that also covers 20-questions API identification.

I'm getting this too on main release Safari... because the test only handles Firefox.
