My experience is that having an actual product can also not bring anything at all.
So maybe this kind of landing page “trick” can't bring you too far. But it can definitely help to see if there's someone interested at all.
Today, the landing generator service page has gotten ten-ish emails. For a product that doesn't exist and for someone without an audience (me). Another one I have has gotten 0.
I'm also suspicious of things like this as a user, but apparently not everyone is. Specially people that are really interested.
