Why doesn't realm server support experimental gameplay?

A few days ago, I thought the realm server supported experimeantal gameplay.

But lately, I knew that realm server does not support it.

Add-on makes the game more colorful and add-on needs experimental gamrplay.

Resource-pack&adding entities works well but items, biomes, structures, functuin command, new craft do not support on realm

These are so important on game play.

Minecraft is a fun game to play together with many people, and the realm server is worth it.

You take a certain amount of monry from minecraft users every month.

This problem has been mentioned for a long time and we hope u can support this feature as soon as possible.

One of the biggest advantages of realm server, the add-on feature, is not supported by experimental play, and is losting its value.

plz solve this problem!
