I'm sure it's easier on the hard drive to not have so many files in a single directory, but it definitely complicates the programming aspects. Not so much that it's impossible, but simply a hassle to look in four different places for a file, just to see if it exists.

I guess once it's standard it won't be any more difficult than it is right now ..., just supporting two layouts at once is a bit of a stinker.
