The bedrock lineage is microsoft's attempt at microsoftifying minecraft. The team behind bedrock are responsible for showing the world the supremacy of DirectX.
Bedrock is far behind on features and is far buggier compared to java edition. A ground up C++ rewrite is noble beginnings. Unfortunately time has shown that they only planned to get it to an MVP necessary for some gross monetization tactics targeting children and not really a genuine interest in improving the tech, growing fandom goodwill, or creating new art.
Because most mods take advantage of Java capabilities, so JavaScript extension points are not as interesting.
However the C++ version has a reason to exist, sadly Java never established itself for gaming outside desktops and J2ME/Android.
One could argue about AOT, but those are not widely adopted, CodenameONE, RobotVM.
I was under the impression it was because Java wouldn’t work on mobile devices. Is that not the case?

But does allow you render distances and frame rates that are impossible with the stock Java game (and can still be tricky even with mods.)
