How do you know that you need to remove:
/usr/local/bin/xxx symlinks
/etc/hosts modifications
/Library/PrivilegedHelperTools/com.docker.vmnetd
after you moved your Docker folder to Bin.
That's only system files, there are also dozens of other files in $HOME.
I guess you can do `find / -name 'docker'` and `grep -iR docker /` but that's a bit ridiculous.
