Entirely possible, I know they have commented before on not wanting to do it.
Which I kind of get if you're parsing metadata, you'd have to create a whole new method for parse and view which can be a pain. Though I'd hardly call it evil myself since its how I sort too.
I'd agree on having to think and duplicates are possible, but that's possible in so many scenarios.

Either way metadata I think is important, but ive been a pain about metadata since the 90s (because burning CDs and having the actual track info was awesome).
