But then you get into "why do you fix glitches?" The only reason to fix a glitch is to improve the game; if there is no improvement no one is going to seriously push to fix a glitch even if Nintendo said so. Arguing about whether or not a designer intended it to be that way is not going to work because that's not what anyone cares about, nor is that remotely verifiable, so ultimately "glitch repair" boils down to "improvement". At which point, the improvements we implement are at best arbitrary, rather than "all improvements" or "improvements only greater than a certain magnitude".
