> Also the "Note" in that section provides a decent argument for supporting `ping`. Basically, users will have their clicks tracked anyway, but the `ping` attribute provides more transparency and a better user experience.

I see this argument used a lot for including user-hostile features in browsers. I don't think it's a good argument since having a browser implementation a) makes this privacy abuse easier and b) legitimizes the practice. Meanwhile as shown in this post, user-preference to disable the feature is ignored and simply worked around by websites.
