Not seeing any advantage, and serious disadvantage. The hiding of the index file name in a folder is kind of a quirk, it's automatic behavior that is being taken advantage of to make "nice" URIs, but it's actually hiding useful information. File extensions, while a DOS/Windows thing, I've found to be an extremely useful convention on unix, and linux, and just about any other system I've used (though I can't remember what we did on VAX box we used to use in the 90s).
