@mwjames There is probably a reason for doing this, i.e. having alias and name being identical?

As far as I remember that was required by the old lang object handling (1.8x) to allow traversing the lookup. It could be that we still rely on it somewhere in the Lang.php when building the mapping between those literals. It shouldn't be necessary but I would have to confirm that which I cannot guarantee to happen anytime soon.
