I don't remember it being in the docs either, as that would have also saved me from signing up on the Discord.
And this isn't an issue of prioritization. Remember, your overworked volunteers and maintainers on the Discord are still spending hours every day fielding questions in #user-support that could have been answered by a link in prominent places. You're wasting more person-hours than you would have with effective communication and trivial updates in prominent places.
You didn't even benefit your own goals by leaving those out!
So no, I guess I don't understand what the huge barrier is to putting out these important notices.
