The VFS itself does not care much about inode numbers. The Posix API does, although btrfs ignores that and seems to get away with that (mostly because applications put in btrfs-specific hacks). Various other non-native file systems that don't support real inodes numbers also get away with that, but usually the applications used on those file systems are very limited.
