I think part of the problem is the assumption that a 25 ft gap should be an obstacle that involves multiple checks.This is so perfectly said.
It starts real early though.
I design a dungeon with a 25ft gap/pit you need to get over. No fighter or rouge of any level is jumping it but a few skill checks and creativity can get someone across and then pull a rope to just hand over hand it.
You can get a hood ten minutes if gaming out of that.. or you can spider climb/mysty step/fly and say done.
So spend time and rp and think or just push a button on your sheet and spend a resource (or not I think you can get spider climb at will)
An arcane locked door has a clue that there is a mystic key on a guard. You can go find the key kill or bribe the guard get the key come back or cast knock.
When you throw around 10+ spells a day you get quite a few of these.
Let's take a 3rd level party. Low level right? How many ways can I cross 25 ft? Plenty. I can cast levitate, misty step, or jump. You can be an eladrin or shadar-kai and teleport. You can be a tabaxi and climb, or a dhampir and spider climb. You can be a druid and wild shape. You can be a fairy or aarakroca and fly. You can be a vhuman with fey-touched and misty step. And I'm SURE I'm missing plenty of options in subclasses and other features. Moral of the story is the game has intentionally made a 25 ft gap trivial. They have done the same for swimming, darkness, and even hunger and thirst.
