Not necessarily. The primary area of growth has been hardware support (i.e., drivers), and that scales quite well.
The main issue is the grown of intra-system interfaces, and you haven't shown that this has happened in anything approaching the levels where we need to worry. If we add a new file system, like btrfs, that doesn't add a whole new set of VFS interfaces, and it's not like we need to worry about communication interfaces between btrfs and ext4....
