[Tux3] Q: inode numbering, and placement on-disk

I'm not sure about a small point in the Tux3 design; please excuse me if
that's written somewhere I just didn't look.
There are some hacks to sort the directory contents by inode number before
doing the stat() calls on the names; it's been proposed in kernel, done via
LD_PRELOAD, and explicitly coded in some applications.
[ I'm interested in that because my pet project (fsvs.tigris.org) uses
a per-inode-number globally-sorted list of entries of whole directory
hierarchies, which makes querying them faster than "find" on cold
Now, if I understand Tux3 design correctly, it's no longer the case that the
inode numbers have any meaning regarding the on-disk location (because of
snapshots, versioning, and other strategies), so this hack (or "feature", if
you like) wouldn't work anymore, would it?
Thank you for your patience and all answers.
