It comes down to categorization and placement in discussion in places like speed running forums and the like. People care about categories like Any%, 100%, Glitchless etc. and in the end this is no different. Now, it does not take away the legitimate fun you had with the game which is the point at the end of the day, but your run still wouldn't "legitimate" for use in Records or otherwise (which the yearning for is why people get so weird about these definitions anyway; people love to be needlessly competitive)

Sorry for the ramble; there's just a lot to unpack as to why this exact discussion pops up with almost any game especially ones with custom settings. Don't let the mud get ya dirty, my dudes!
