[support] Changing Role Labels

Before I break something (and then someone breaks my legs), I am wondering if it is okay if I change the actual text names of the various [Roles] which are marked 'locked'?

Specifically, if I alter the values in the `name` column of the `role` table (`rid` 1 and 2) to change "anonymous user" and "authenticated user" to something else, is that going to cause access problems?

(I really do believe it will not be a problem, since language localization and relational design principles would suggest that the `rid` (role id) is the principle match column for determining access.

Can someone confirm before I make a change on an active site?
