It’s interesting that every streamer-era series has ended laying possible seeds for future threads, in a way that the older shows didn’t. LDS sets up Starfleet exploration of alternate realities; PIC sets up Legacy (regardless of it actually happening), and had already set up the idea of the Jurati Borg joining the Federation; Prodigy sets up Janeway’s “special agents crew”; DISCO sets up Starfleet Academy and whatever might happen in the “Calypso” era. Even if they’re not acted upon by future producers, they all actively open doors.
