Personally, I don't care enough. Mostly my kids watch SpongeBob, and I can tell when vaguely paying attention as they watch it that I've seen every episode in seasons 1-3 (the only seasons I bothered to load) multiple times, which would specifically have been when I was a kid watching live TV. And half the time it's on shuffle anyways so the order doesn't matter at all

Edit to add: not sure if the issues people are describing are Plex specific but Jellyfin required zero manual effort when I injested the rips. All episodes have correct metadata (as two parters, so for example I have "S1E10-11 Pizza Delivery / Home Sweet Pineapple" as a single episode)
