Considering it’s in a double tidally locked orbit with its own moon Charon and the point that both rotate around is outside Pluto’s volume I would argue that the Pluto/Charon system is actually a dwarf-binary-planet.
At that point the only really ‘planety’ thing about is is basically that it is spherical.
Its not primarily orbiting the sun, so much as it is the barycenter of itself and charon.
And there are moons that are bigger, and more spherical, and more massive than Pluto.
And while it does have the vaguely heart shaped terrain feature, Mars has a smiley face crater, Saturn has an eternal hexagon on its north and south poles, despite being a gas giant, Jupiter has the spot, Mimas kinda looks like the Death Star, etc.

I’d okay with that. As long as it’s still technically a planet. (what? it’s my favorite!)
