A major benefit of the Btrfs layout is these are subvolumes, which instead draw space from one volume pool. And that's lost with a conversion strategy. It also means going from a Fedora "standard" layout to a distinctly non-standard one because our Btrfs layout isn't like the result you'd get from what you're talking about.

        A question I have, forgive me if it seems stupid, is why not
        just change the standard? From what I have seen is that btrfs is
        superior to ext4 as even Theodore T'so (creator of ext4) said
        btrfs "offers improvements in scalability, reliability, and ease
        of management". I feel that eventually other filesystems may
        show to be better than ext4 and we probably will need to change
        the standards for the sake of quality. My fear is that we will
        be sacrificing quality for not having too change much.
