This could also be cosmetic. You cannot reuse the space until the file is really gone. I agree that it's a nice optimization for when your filesystem is almost full, but I don't think it is worth the complexity.
Unless, of course, someone can produce a piece of code that does all this in such a simple and elegant way that we all want to have it in the kernel... (if only because of it's elegance ;)
