I don't actually know what Seinfeld would have been like if it had kept going, because honestly on paper some of the episodes in 8 and 9 are absolute dumbass nonsense and feel like shark jumps, but they're some of the best episodes in the entire series. Same with some of the characters introduced. I always forget Putty didn't become a recurring character until near the end of the show, he feels like a staple.
So like...yeah I just don't know how far it would have had to go before the supports fell lit from under it, because it sure felt like those supports were holding strong.
