Make Bedrock Commands actually Good

So, bedrock commands are seriously limited. Any map maker / command block enthusiast will know that some stuff is just completely off the table, while on Java you can do literally anything, and us bedrock players want to do those things as well. Two large things I want to suggest is things like NBT data manipulation / addition as well as the /attribute command but thats just. I understand that the data thing may be hard to implement but please. Something along those lines would be absolutely amazing for bedrock command block user.
