For example, if https://github.com/pytorch/pytorch/issues/111111 can be seen but https://github.com/pytorch/pytorch/issues/111110 can't, someone might infer the existence of a hidden issue relating to a critical security problem.

Whereas if the URL was instead https://github.com/pytorch/pytorch/issues/761500e0-0070-4c0d... that risk would be avoided.
