Improvement FAWE (Fast async world edit)

There are FAWE commands that are banned and i don't know why, like //br rock. Id also like to add for the builders in cf for a better //br height tool. but we have access to it because we cant put in links. Also I'd like to mention schematics. If we were able to save and upload schematics that'd be a huge thing for builders. Also i know Carlec talked about but id like to add to it with other commands.
In general some banned commands in worldedit should be added

If these commands or many other banned commands in worldedit were added it make such a difference. Thank you for your time

-example for //br height with a command
//br height 5
-example for //br rock
//br rock stone 10 5
