There are not four seasons of Star Trek: The Original Series.
Not watching all of the specials does not mean I’ve only watched three-quarters of the show.
Yes, the original pilot is important enough to require having a season zero for the show.
No, I don’t want to auto-play every special after the final show of the last season of any show.
Seriously, it’s not helpful to have every TV show have a wrong season count, and it’s not appropriate to treat the content in season zero of any show as just part of the show. Season zero is a kludge to allow us to have the extras available, but should be ignored for season counts and auto-play. Please.
