And it has permissions associated with these hashes.

No, with the files.  Think again: the link between file system and
repository is the index, and the current index format has no
representation for trees or directories.

So git _can't_ store any information about a _directory_, since no
information about directories passes through the index.

If, as Jan suggested in a previous message, you introduce
directories in the index, I still don't see why you would need two
entries in the tree object...

As I already said: you don't.  It may just be _convenient_ in the
_index_ for doing single pass merge collision detection (when a
directory is replaced by a file or vice versa).  But there would be no
additional information stored in the index, and it definitely would
not be worth to do double entries in the repository: the repository is
already capable of representing all the desired information and it
would be wasteful to introduce any complications there when the
current format already is fine.
