Instead of redirecting stderr, wouldn't supplying an explicit -in /dev/stdin be cleaner?

Not sure it is as compatible, but would probably also work.

It seems for openssl they are acknowledging that the error message was a bad idea will only output if stdin is actually a tty, so this will hopefully become obsolete.
