Reverting exported settings miss out on core roles with different locale

If I export a profile from an English language installation and import that profile into an installation with a different default language, the "authenticated user" and "anonymous user" settings are lost.

This is due to the fact that user_roles() returns a localized role name, and the CKEditor Features code uses role names, not rids.

I could submit a patch to modify the Features export/import code to use rids instead of role names, but I was wondering if there's a reason for using role names in the first place.
