That was linked too. It's useless, but I guess it depends on your definition of "verify". An account existing doesn't mean it's the right address, it could still be mistyped, misremembered, or especially intentionally wrong because it does literally nothing to stop that. It doesn't even mean it actually exists, it could be one of those 1-minute temporary inboxes. It would catch some typos I suppose.
I would definitely not consider the address "verified" after this. "Verified for spam purposes" perhaps.
