That reminds me of Chrom[e|ium]'s insanely bad form suggest/autofill logic: The browser creates some sort of fuzzy hash/fingerprint of the forms you visit, and uses that with some Google black box to "crowdsource" what kinds of field-data to suggest... even when both the user and the web-designer try to stop it.
For example, imagine you're editing a list of Customers, and Chrome keeps trying to trick you into entering your own "first name" and "last name" whenever you add or edit an entry. For a while developers could stop that with autocomplete="off" and then Chromium deliberately put in code to ignore it.
I'm not sure how much of a privacy leak those form-fingerprints are, but they are presumptively shady when the developers ignore countless detailed complaints over many years in order to keep the behavior.

To be fair, websites with a horrible misunderstanding of security kept on using that for "this password is important, better make sure the user is forced to enter it by hand!"
