Parity with Java, Bedrock, and Legacy. (Re-adding features!)

What I want done/Why I want it done:

For years Minecraft has been split into 3 versions, Java, Legacy (now discontinued), and Bedrock. But there's never really been good consistency. All versions always have features that don't exist on one version but do on the other, and Legacy has many features that don't exist anymore for no good reason. So my idea to re-add features from legacy, add features from Java to Bedrock, and honestly make Bedrock a version of Minecraft to go down in the history books.  A way to make Parity between Legacy and Java/Bedrock would be to add a First-Party server re-adding minigames to Minecraft. You could also find a way to make the two versions Cross-Compatible with this one server, (ThirdParty Java ones have done it!). Another feature is to re-add Old Worlds back. There's something fun about being restricted to this one small world trying to get all the fun you can out of it. Sometimes Infinite worlds are just too overwhelming. The next feature to add to bedrock from Java and Legacy is to add amplified worlds to Minecraft Bedrock. Also, add Exit Without Saving

How I want it done:

A good idea would to make something like 1.22 the Parity update. Make Parity between all three versions as one nice big update even including new features. I'm not asking for Legacy to be updated but to have features from it brought to the new versions of Minecraft as a way to get people to stop asking for it to be updated.

And a final thing, moderate the Marketplace properly.
