As mentioned in the email thread, this approach sounds good to me. However, I would love for the UI to be very explicit about what's going on, even as compared to the PSL matching UI. The extreme version is that the drop-down would say "Chrome sees you have a credential for foo.com, which we know is associated with bar.com. Would you like to use the bar.com credential here?" Obviously, that's way too verbose, but you get the idea :-)

Thanks, jww@. I think I need to speak to hwi@ about how to best get that message through.

I started an e-mail conversation with hwi@ about this.

Also, I'm marking this as blocking issue 611751, because once with adding more use-cases for affiliation, we might need to care sooner about exceeding the quota.

Turns out, the web<-->web affiliation is only supported for cases where also an app is involved. That should not cause us to exceed the quota mentioned in #2 soooner.

I'll reach out to jww@, vabr@ and other folks once I start exploring design options in August. Thanks!
