Yeah, but only for their first post, and the notice is purely
advisory anyway.

Well, I don't know about "lots".  We'd only get the spurious warnings
for those abandoned edits that came from people on browsers that
already have an Author cookie set.

But since this is going to be an optional recipe anyway, the
way to get some real data is to implement it and people can
install it if they like and report back on the results.  I'm
sure we'll hear about the cases where it's not working as
one would like.  :-)
