This bug has an owner, thus, it's been triaged. Changing status to "assigned".

Does it make sense to simply validate that the form is at an HTTP(S) origin?

I.e., instead of excluding the chrome scheme, only include http and https schemes?

Does that mean that we would not send queries or votes for address forms that are HTTP?

No, it means we would ONLY send queries and votes for HTTP and HTTPS.

Ahh perfect! I read too fast :)
