Agreed, realistically in actual play deploying traps as a 5e gm just feels like a waste of everyone's time. I say that as a gm who has in the past used them for amazing results like
this, but
that 100% depends on forcibly teaching the players to take the metaphorical baton and run with it with zero support from the system&rulebooks for either side of the gm screen. The whole thing collapses into a multi mile car pileup or an annoying rail roaded QuickTime event where the gm tells a story if the players don't confidently take off like Usain bolt without stumbling even a tad the second they get offered the baton by their gm. Back in3.xI could tell them they guess it's an insane DC & show them the
dm's best friend entry to get the ball honestly rolling with interest, but doing that with 5e tends to provoke a "
I want to play 5e not some other edition, wotc playtested what's fun & must have had a reason to leave that out"* flavor of active willful refusal
* I put that in quotes because it's very close to what I had a player once say when I tried it after shooting down "I want to roll x".
