There's a lot of room for interpretation. "An idea" doesn't necessarily mean revisiting something we've seen before. And candidly I hope that's what it is. "Lolani" took "an idea" from TOS and fleshed it out a bit and in a way that didn't feel mired in the past.
What "Lolani" did felt much fresher than "Pilgrim Of Eternity." I hope they continue that approach rather than just revisiting previous characters and stories.
