Why does everything need a waitlist now?

It seems like JetBrains created a new tool called Grazie, which works like Grammarly, but also offers auto completion and other features.

(Now the AIs want to control how we talk! LOL)

Anyway, they have a wait list too. And you know what? I got acceded almost immediately after I enrolled the wait list.

Then why setup the wait list in the first place? Why use a waitlist if not too many people are whelming in your product?
