Provides the most simple/stupid internal user database - an array of
usernames and passwords and permission/ring levels. This is useful if
you only have a small group of active users, because it simplifies
user management to editing this plugin file (adding users and changing
passwords or permissions inside its PHP data array).

next >> "userdb_systempasswd"

You cannot modify the ProtectedMode file, but anyhow any ideas or suggestion should as usually get filed on BugReports, UserSuggestions or even better the ProtectedMode.Discussion.
