Why not continue to improve the Script Engine?

I have something to say: I was really looking forward to Script Engine before it was released. But in recent updates to Minecraft, I found that there was less and less content about Script Engine.

As we all know, Bedrock Edition accounts for a large part of the players, but now Bedrock Edition's mod is not perfect, I hope your company can attach more importance to the role of Mod in the game, rather than just adding game content.

Therefore, I would like to make the following suggestions:
1.It's essential to make the Script Engine able to add blocks, items, etc. There are limitations in replacing game content only, which largely limits the imagination of Mod developers.
2.Make the Script Engine able to modify the game content to the greatest extent possible.
3.Perfect the API of Script Engine to make it easier for Mod developers to develop.

Note that this is only for Bedrock Edition.I know it's difficult. If this is done, many systems need to be rewritten.But it can make the game live longer.

So please consider these suggestions carefully. Thank you.
