@tux-rampage I had removed this because I was planning to remove the "`addRole` with parents".

As @weierophinney said, we cannot remove the "`addRole` with parents" to keep BC. Then I restored and deprecated the methods beucase I want to deprecate the "`addRole` with parents" functionality since this doesn't makes any sense.

What about deprecate `addRoleWithParents` too?
