I like this idea!

Just a small suggestion:

"btrfs remove" instead of "btrfs rem"

Another question: Is there a simple way to convert a directory into a subvolume?

Currently I first create the new subvolume; copy or move the data of the
directory into the new subvolume, then delete the directory and finally
rename the subvolume.
