Because names are no longer a unique way to identify players for longterm datastorage, that is the uuid that the core systems have switched to for storing player information - if you change your acccount name on mojang, the permissions will still recognize "you" despite the name change. It should only be within the internal system of the permission file, and not be visible to you anywhere else.
What if i have, let's say, 300 players on my server with a different rank, how should i know who is who? EDIT: Wait, can you change your name on mojang?
perhaps its time to change from permissions bukkit to some other permission system which stores by uuid, but also shows the name in the file... Yes, since Feb 4, players are able to change their account names once per 30 days.
