Should Pluto be a planet after all ?

Pluto may have been demoted but it turns out it is the largest body in the outer solar system after all.
Back in 2006 Pluto was demoted to the status of "dwarf planet" following the discovery of other objects in the outer solar system such as Eris which was thought to be larger. Now it appears that Eris isn't larger than Pluto at all - so should Pluto now regain its original status as a planet ?
Now that Pluto may have regained its status as the largest object in the outer solar system, should astronomers consider giving it back another former title — that of full-fledged planet?

Imo pluto should have just been left as it was but it dont matter really cos pluto is still there and will be for eons to come, dwarf or full status, Actually, in the perihelium, 4,41 Billion km, Pluto is closer to Uranus than to Neptune, which Kuiper belt object can brag about that? All the Kuiper belt objects have their whole orbit well outside the Solar system. Pluto is on the inside, for most of its orbit. The only criteria that Pluto did not meet for being classified as a Planet, was the criteria that require a planet to have "cleared its path", meaning it is dominating its orbit with no ... [More]
