For the nth time, it isn't a subjective judgment call about what is or isn't a planet. There's a definition. Look it up, apply it to the situation, and come to a conclusion.

With the current model it has cleared it's orbit and is round so it would still be a planet.

With the often speculated improved definition it is round and also was geologically active and so would still be a planet.

Size isn’t everything.

Mercury orbits its star, has cleared its orbit and has collapsed into a spheroid under its own gravity.

Titan and Ganymede orbit planets and thus are moons.

The five planets were defined in prehistory, including Mercury.
