Maybe though you meant this specific type of "non-malicious" MiTM and the
problem is we don't have a name for that right now.

If you meant all MiTM though, your solution only only stops attackers who
wants to make it look like you're interacting with the real site, not one
who merely wishes to steal your data.  In that case they don't have to talk
to the real wells-fargo website :)

This is exactly why some people are pushing so hard for protocols that get
"exclusion" including things like CA-Pinning in Chrome, CAA, etc...
