Ok, but a part of my point is that the ability to perform a task as a bonus action should imply that it takes a very short amount of time to make the check, even outside of combat, right? So if, as in the original post (so long, long ago), the DM wants to say "ok, the check takes 1 minute, a retry takes 5 minutes" and so on, what does that mean for a Thief?
Because it doesn't really make sense that a Thief can do something in combat along with a normal action and movement inside of 6 seconds, but out of combat, suddenly it takes 10x that amount of time or longer.
