Nope, can't agree. From where I'm standing, proficiency and expertise bonuses on skill checks are too small. Way, way too small.
Imagine a person who's never driven a car, never taken driver's ed, no training at all. Take that person, plunk them behind the wheel, show them the pedals to make it go, and send them down the interstate. What are the chances that they reach their destination without a wreck? If you put that chance at 50%, you're more optimistic than I am.
Now, take a typical driver--not a race car driver or a long-haul trucker, just Joe Average Commuter--and send them down the interstate. What are the chances that that person makes it safely? If you say 95%, you are asserting that the typical commuter (two trips per day, 5 days a week) wrecks their car twice a month! I'd hate to see insurance premiums on the D&D highway system.
But think about what this means in terms of the d20 scale: If the average trained driver has a 95% chance to make a check that the average untrained driver fails 50% of the time, that implies a proficiency bonus of +9. That's just proficiency, not even expertise (expertise would be a professional driver of some kind).
Proficiency bonuses in D&D are laughably tiny. And yet people keep complaining and wanting them to be even smaller! Bounded accuracy is designed for combat, where the attack roll is just one component of a much larger system. It makes no sense for skills.
