You might get away with backpathing over symlinks if you URL-encode the
.. segments, like foo/%2E%2E/bar. If I recall correctly, the URL
decoding is done *after* the canonicalisation, at least in some cases
(checkout-cmd). Well, OK, this is probably a bug, but I don't see a way
to fix it safely with the current flow control.

That aside, it's very risky to try backpathing over symlinks. Several
levels may shortcut out there, the bash does it for instance in a very
elaborate way so that even "cd .." most often backtracks to the symlink
