It’s really there already. All they need now is QOL onboarding features like an in web browser version with a QR code to join your friends’ servers, or if they could get on nintendo switch or something (not going to happen, but I can dream)
I have to dual boot windows on my PC mainly so my brother can play minecraft (bedrock, java ofc is fine) and roblox on it because the linux support for both is really spotty 
https://www.luanti.org/ is a near perfect minecraft clone, better actually in some ways. Setting up a server for example is cake when you don’t have to worry about DRM or authentication whatsoever. Every instance is a server with a click of a button. If the server is running mods your client will automatically download them proper mods to match.
The only thing it’s missing is the huge library of mods minecraft has, but It’s easier to make mods for Luanti than minecraft since it’s open source.
It’s more than just a mincraft clone, they’re angling to be the open source minecraft + roblox all rolled into one. It’s already better as a base game than either.
I’m aware of the ones running the android version. They run well when they do, but online is partially broken and they crash frequently.
