No. It’s smaller than other moons in our solar system. It’s never going to be a planet again, but a planetoid, dwarf planet, or even asteroid is appropriate.

Just to be pedantic, Mercury is also "smaller than other moons in our solar system"

And never is a long time, especially for something as fickle as human classification.

You’re right, it’s about gravitational domination.

Agreed.

My (uninformed) guess is they will eventually reclassify all non-moon objects in hydrostatic equilibrium (anything round) as planets, which will make Pluto a planet again and bring in a half-dozen new objects.
