My experience is that I have been in companies where some people were spending a ton of time doing that kind of "clever tricks", and it never brought anything at all.

My opinion is that it must be hard to get visibility for a landing page to a product that does not exist.

Side-effect: I don't believe anything businesses say unless I can see an actual product, because such marketing schemes trained me to be suspicious of everything. Businesses lie, except when they don't (which is rare).
