Once a DM knows to do that, and some of the spells are not the ones you would expect.Not to mention that they're likely changing Banishment so that the target gets a save every round. There are another handful of spells like Forcecage that can trap creatures which IMHO are even worse. It's easy enough to ban those handful of problematic spells if they're making the game unbalanced of course.
But the assumption is always that wizards (and the people who play them) are like Batman with the correct spell always prepared and the spell slot available to win the day. I've seen it once in a blue moon, but I've played multiple games to 20th level now and it's rare. On the rare occasions when it does work it's fantastic and everybody cheers. Different classes have different roles. I want to maintain that distinction.
You don't need the "perfect" spell for any occasion. The wizard has more than enough slots to have a very useful and broad selection any given day. Heck in the last 2 adventures (where I got to play!) the two MVPs were minor illusion and enhance ability - easy choices.
