Please don't do that. Reading the passphrase from its special file
descriptor may not be an ideal solution but it's certainly WAY better than
to do a send/expect kind of thing.
I think the main reason it's documented as not ideal is because you can
only read one passphrase that way -- but that can be fixed. Currently, gpg
reads the passphrase from the file descriptor once, right at startup. A
better idea would be to send a special message to the status FD whenever
gpg is waiting for a passphrase, and then read one line from the passphrase
If Werner says he'd accept a patch for this, I'll implement it.

have written that."
