A reflink would be a new type of inode only in so far as the filesystem must track the fact that it has blocks shared with another inode. There is no difference, though, between an inode created by a reflink and the file's original inode; they both become reflink inodes. In Btrfs, I believe, things are even less different; the tracking of the shared blocks is done at the extent level.
