The astronomers really could care less. It's a social construct more than anything. But IMO, it never deserved to be called a planet to begin with. You put that thing near the orbit of Mars, it would burn off to be less than a tenth of its size and it would grow a tail like a comet.
As if it wasn't confusing enough that sometimes it's the furthest planet from the sun, and sometimes it's Neptune...
I think it's classified just like Pluto: a dwarf planet. Charon and Pluto are also, in effect, classified as a double object -- like a double star -- since the center of orbit between Charon and Pluto is really located between the two objects. Even if they still (errantly) call Charon Pluto's "moon".
