Should Veil expect the email address along with the verification string to complete authentication?

[armanm]

I recently had to work on an auth solution using Firebase Password-less authentication which is why I'm curious to raise this question about Veil:

If you look at Firebases' security concerns they suggest that the verification string should always be accompanied by the email address at the time of sign in:

To prevent a sign-in link from being used to sign in as an unintended user or on an unintended device, Firebase Auth requires the user's email address to be provided when completing the sign-in flow. For sign-in to succeed, this email address must match the address to which the sign-in link was originally sent.

I'm curious what you think about this requirement and whether that's something Veil should support?
