Make commands equal

I'm not the best at commands but whenever I do try something it doesn't work, why? Cause all commands that I need are java only, I understand that bedrock is easier on all devices, but like the feature (that I personally love) that allows us to copy coordinates, I would love to be able to enable complex commands, so I would be able to choose between an optimized version and all commands, I understand that it might be a little hard to implement some, but there are so many seemingly easy commands that I doubt are difficult to implement into bedrock, please don't remove anything from java to make it equal, the more the better. :)
