While I agree that it's a concern, I'm not overly worried that this is
going to be abused for a few reasons.

1) We talked to some major US banks when disabling autocomplete=off for
passwords, and though they historically have been a big proponent of the
feature they didn't seem bothered that it was no longer going to be
respected. It seems like sites are more accepting of password managers now.
I wouldn't be surprised if a reasonable percentage of autocomplete=off
usage is just inertia at this point.
2) A well-intentioned site might use autocomplete=off thinking that it's a
security benefit to their site. Doing this with this new API would be
obvious abuse and it doesn't seem likely that a site would do it unless
they were looking for some way to block password managers.
3) If a site really wants to go out of their way to make sure that password
managers don't work on their site, there are already ways of doing it. This
would be an easier mechanism, but I'm not sure how much that matters.

If we still think that this is too likely to be abused, another possibility
might be to only allow the site to assert login succeeded not that it
failed. Not sure how useful that is though, since it's generally easier to
prompt on incorrect login than miss a correct login.

In most of the cases that I've seen where this comes up (e.g. Pandora) it
seems like the entire site does navigation via AJAX + history.pushState().
It doesn't seem like the site is trying to avoid password managers so much
as they are trying to keep the aesthetic of their site consistent.
