That was probably their intention, but Bedrock has proven to be full of papercut sized bugs, and maintaining 1:1 behaviour with Java has also proven really difficult. Redstone is notably different/broken with the exception of trivial circuits.

Until it's possible to convert your world to Bedrock and not have anything in your 'finished' world break, except maybe some giant Redstone machine or one or two known annoyanced, I doubt they'd do it. Mojang presumably still has some autonomy within Microsoft so long as the money keeps coming in, and Mojang presumably knows that pushing this too early is a bad idea. But Microsoft being Microslop, who knows, maybe they'll just do it anyway.

I don't think 1:1 behaviour with Java was ever the intent. Redstone works differently due to a combination of different design choices, like not breaking in water (although I can imagine that being an accessibility thing for console players) and less technical debt, making things like movable tile entities possible.
