Hook players on what premise? It's never been intended to have 20-50 people playing on a server. Ever.
It has never been intended in Ark that flyers are the only way of transport, yet it happened.
Just imagine if they hard-capped servers to 8 players. What would you do then?
Mod it out and create a bad steam review (Ark temporarily fell down to 30%)
The point of the matter is that everyone hosting a server with over the supported player count is violating the feature of the game. (Guilty as charge too, because I set mine to 10 players.)
So just because we MIGHT experience a bug (personally never had a problem with 50 player+ servers) we should not be allowed to play that way? Why not simply create a warning "Warning: You exceed the max amount of players/mapsize. If you continue, the game might get buggy."
The backlash would only come from people who have no understanding of what the game is meant to be, and are trying to make it like all the other games they play. This isn't CoD, Battlefield, or Rust.
Players have their own minds. You cannot tell them how to play the game. If you want your game to be a certain way, but it has istablished its own rules on its own, then you can make "your way" the standart option and the "other way" a secondary option.
