I thought graceful degradation in terms of web design was mostly just to promote using the latest current browser features but to allow it to fall back to the feature set of, say, 1 or 2 previous browser versions. Not to support a user completely turning off a feature that has been around for literal decades? I think what you’re promoting is the “opposite” side, progressive enhancement, where the website should mostly work through the most basic, initial features and then have advanced features added later for supported browsers.
Thanks for the response, good points all around. The fingerprinting is the most convincing argument to me but I think the accessibility issue you bring up is more important.
