This is also why I very seldom use other DC's than 10 or 15. I might sneak in a 20 now and
With my high level game I like saying stuff like "OK Rogue, you auto spot the DC 25 secret
door with your passive per" and "OK Barbarians, with your minimum 20+s on Athletics you have no trouble steering the canoe for hours down the foaming rapids" or even "DC 28 to break open the fortress gates - so you rip them off their hinges..." - definitely feels super-heroic, and lets the players see how far they've come. Conversely, even level 20 5e PCs can still be beaten up by a few giants, and need to play smart.
