Note: various utilities/services with command line parameters needed to be
updated due to the changes mentioned above. The downside is that these are
not backward compatible. Unknown arguments are no ignored. Only bound
arguments will be treated.
Thanks to Mark McLoughlin for migration cli code changes.
