That's probably a pretty common summary even for newer players/gms. I can only guess, but think that
@Lanefan might have been knocking the near fetishization in recent years when it comes to reflexively jumping from "x can be a problem" to declaring that it can't be a problem because the GM & GM alone is responsible for covering that in session zero.
Personally I've tried running what was explicitly called "session zero" because I was tired of hearing a couple players grumble "well that
[unforeseen edge case☆ that needs a ruling bob doesn't like] should have been covered in a session zero". Made a big deal about it & how the players should bring up anything they feel is important to clear up before we start another campaign. Unsurprisingly the grumblers had nothing to bring up.
☆One example was that after selling multiple looted fire resist items in earlier levels the players (led by Bob) decided that they were going to refuse to fight the dragon they had known about as a problem for months of lower level real world weekly sessions unless they took the time to make fire resist items. The fastest way to obtain the needed components from elementals was to attack a nature shrine/temple type thing & kill the elementals. Players were outraged that immediately taking a long rest in the desecrated temple resulted in a plague of stinging/biting insects that prevented a successful long rest the whole way back to town and that was never covered in session zero.
