That would surely be a good thing, because it would mean the new series wouldn't be just a rehash of the original's tropes and ground rules, but would be something new. That was the whole point of the finale -- that it changed the way things had always been done and created a whole new status quo. It would be a betrayal of that ending, a failure of imagination, and an act of intellectual cowardice to hit a reset button on that revolutionary change and retreat to just rehashing what was done before.
Indeed, it would be worse than that, since giving the Potentials that power was a feminist allegory, breaking free of the domination of the patriarchy and giving a whole generation of girls the chance to be truly independent in a way a single Slayer couldn't be. Resetting that to the old status quo would be a horrible, horrible statement to send to the audience. The whole point of the final season is that being the "Chosen One" is a trap, not a privilege, because it means you're not the one making your own choices, but are having them made for you. So it should absolutely be abandoned in the new series.
