Based on Tarantino's interview, he comes off as a casual fan only, not one who has memorized all of the episodes and the lingo. There's definitely a fondness for it, but it's not obssessive/otaku-grade. This would probably prevent him from taking things down a fanservice continuity-porn direction. It would be a story that thematically is Star Trek but very loosely bound to continuity. Almost like a Tarantino fever-dream. Could be quite engaging as a one-off experiment but it would be a hard sell if the suits at Paramount proclaimed it 100% canonical just as a lot of people won't swallow Discovery as canon.
