Yes, the Earth cannot be a main priority for the Homeworld, if it was, the Homeworld would have easily steamrolled Crystal Gem resistance. Now there's just 4 gems protecting the entire planet, and it would be a cakewalk for the Homeworld to take it back, especially considering that Rose is no longer there (or... Is, but Steven is still learning.)

If Earth was a main priority, the Homeworld would have sent far more than just a few scouts there. Especially considering that before the events of 'Warp Tour', they did not even know that the Crystal Gems were on the planet, meaning that resistance was nonexistant in their eyes.
