There's no update currently; I think there's some amount of consensus that this approach, while fixing the issue, would cause too much other collateral issues.

I'm considering making a patch that switches to hashing the canonicalized path, for the cases where we know the path isn't a local path; it's not an entirely correct solution, but a rough approximation for when the file IDs are stable or not. I just haven't had time to try doing that yet.
