Could you post an URL to this discussion, so that I can view the reasons
brought forth?

But this could happen anyways. One example is the read-only share case,
another one is a directory to which the user has no (Unix) write rights.

suddenly become wrong, making samba less dependable.

more about ego than about "To serve our users best".
