Game Rule alterations, Render Distance, and other stuff for Java Realms.

Currently, there is no way to alter the render/simulation distance in Realms. I believe that the default should be able to be set by the Realm Admin/host/whatever, the the invited players can alter their own render distance on a player by player basis for their own views and needs. It's frustrating not being able to see large portions of the map and important landmarks because of lacking render distance.

Also lacking is the ability to alter Game Rules for Realms, such as changing Entity Cramming, disabling/enabling Raids, Random Tick Speed rate and so on.

All of this makes paying for a Realm seem pointless, and drives up the need for 3rd party software. This sort of thing should be expected in 1.20, and should be the norm.
All of this is in Single Player Servers, and 3rd Party Multiplayer Servers. Why is it not in the payed for, seemingly Official Multiplayer Servers?
