It sort of depends who you ask. Personally, I see value in being compatible with as wide range of kernels as possible in a development filesystem that you want people to be testing. But then I'm not doing any btrfs development, so I don't count for much.

Please put this somewhere else, a separate file and hopefully only in your backports tree. This is kernels from stoneage after all, not just one or two revisions back.
