Yep though in Metroid Prime Hunters all the other hunters have some functionality that mimics it.

Also she can freely switch between the full suit and Zero suit damn near instantly. So she is almost never with out the suit. Tthe main time is when she loses her suit in zero mission and gets a more complete version of it from a chozo ruin after sneaking and crawling through a space pirate base

Yep and the suit has mostly grown back in Dread because Chozo tech is insane. The suit can also adapt a lot of other tech in to it that did not come from the Chozo. the Luminoth, space pirate tech on occasion, Galactic Federation tech, and Lamorn tech to name a few.
