For the Light Dragon to follow the "named after a goddess" pattern, she would need to be named after Hylia ... which would also be fitting, considering who she actually IS. But that would probably have been too much of a spoiler, I guess?

Still, something like Hyliana, Lhyana or maybe Hylin would have been nicer than just "Light Dragon". It's weird that that this dragon was allegedly floating around the sky over Hyrule for a whole century, yet noone ever gave her a name.

...alternatively, she could have been named after Ordona who, along with "Faron", "Eldin", and "Lanayru" was the Light Spirit Guardian of the Ordon Province in Twilight Princess. Not exactly the same as a goddess, but part of a quintet of equally mighty spiritual beings of which 3 are named after the Golden Goddesses already.
