What is your current rclone version (output from rclone version)?

rclone v1.62.2

• os/type: linux
• os/arch: amd64
• go/version: go1.20.2

What problem are you are trying to solve?

delete the root directory after completed move if the folder is empty. There will be some cases that can be left files when using filters.
rclone move /local/test/dir remote:bucket/test/dir
the folder /local/test/dir is leaved empty.

How do you think rclone should be changed to solve that?

just remove the root directory if the folder is empty. --leave-root=false flag as @ncw noted.

rclone move /local/test/dir remote:bucket/test/dir --no-traverse --fast-list --delete-empty-src-dirs --leave-root=false -v -P
