I propose a warning... "For security reasons, all versions of Internet Explorer are no longer supported. Please upgrade to a modern/current browser such as Chrome, Firefox or Edge."

Make sure to state "For security reasons" policies always have that even when it's not true, or bad security, because most people don't question it.

That would scare the hell out of my users and immediately increase support volume by a not insignificant amount. There's not a lot of sense in doing that anyways since many/most of the users stuck on old browser versions are stuck due to corporate policy.

Then their corporations are running old/insecure browsers... the end. It's not my job to coddle corporations that are endangering their own users.

Yes, actually, if that's who you are selling your product to it is exactly your job to be doing that.
