I am posting this message primarily to let maintainers of userspace su-like programs know that they should in fact proceed to implement allocation of a separate pty, if they don’t do that already. Do not wait for the kernel to do some magic thing because it’s been NAK’ed, it wouldn’t fully address the issue, and it wouldn’t be enabled by default.
