Whatever happened to Radaghast?

The ship Gandalf, Galadriel, and Frodo took wasn't the last, btw. Legolas, Celeborn, and some would say Gimli and Sam all sailed west, too, at some point.

Quite true, but it is not said that he was on that ship either. I don't believe he never returned to Valinor, he must have at some point, IMO. He was a Maia and had the right to go there, I think, in body or in spirit (if killed), unless banned, like Saruman and Sauron.
I don't think Radagast deserved to be banned.
