I've seen quite a few. One recent example is bug-assist.js — a script 
that makes it easy for readers of a document to file bugs about it — 
that looks for all metadata names that start with "bug." and uses the 
remainder of the name as parameters to a Bugzilla bug entry.

I am not aware of specific cases in which the browser is acting on the 
names, but there are quite a few in which a third-party system is (e.g. 
when using those as checks that a given person really has access to a 
given site).

The point is often that the person seeing the validity error is not the 
same person who defined the metadata name. Yes, you can register on 
behalf of someone else, but it's a hurdle and it's not the right social 
mechanics. It doesn't seem to buy anyone much, either.

They're not cruft, they're product-specific. In many cases some data-* 
attributes would be better, but they're not what's used.

Going that far might be a bit much, but if there concern is that typos 
in names then a warning should do the trick.
