But you're talking about a symlink, which is precisly an abstraction in
the FS. That is, the application doesn't know it's accessing a symlink,
so there's to interpretation of .. at all.
When in a/b, and I ask a link z to ../x, I'm lexically asking my shell
to create a link a/b/z to a/x. There is no need for the system to keep
track that it was ../x at the time of it's creation, AFAIK.

Would you really set up file links in a version controlled directory
hierarchy in a way that lexical directory ascending wouldn't make it to
the root of the working copy?

I'm not really convinced so far by the need of a physical .. entry.
Curiously,
