Reducing differences between Java and bedrock edition

I think it was interesting to see video posts about Bedrock vs Java features. But I think that such functions could easily be included in, for example, Java Edition.

-A little texture first (something simple)
Why don't shorn lambs retain their color? In BE, this is basic and I don't think it would be difficult to put it in the other edition.

-The cauldrons
This is a little more complex than the appearance of the lambs. But that makes it even more interesting. In terms of interaction with potions, this would be a big improvement, opening up to the cauldron as well.

- Another example out of many. The bad omen effect. It's pretty spectacular and could really get into JA.

1.21 would be a great time to add these features.
In order to make it as good as possible for as many people as possible, settings could be included that, for example, can be switched on and off from the above examples, which are optional. The bad omen effect or the lambs are actually aesthetic novelties.

If hardcore will be available on both, then these could be dealt with as well.

Yes, and frankly, if there is something in JA, it could be transferred to BE.

Now I'm thinking about the most familiar and important mechanics and features, not the smallest things.

I hope I managed to describe what I wanted well. Thanks for reading and have a nice day.
