[hashcash] minting stamps - stdout or stderr?

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA256

if i run:
        hashcash -Xmr abc@xyz

i get:
        time estimate: 2 seconds
        X-Hashcash: 1:20:040826:abc@xyz::7786d0bc00d5b90c:17c630

all output is sent to stderr. but if i run:
        hashcash -qXmr abc@xyz

then all output (which is just the stamp) is sent to stdout.

aside from the inconsistency that "-q" causes, shouldn't it send the "time estimate" to stderr, and the stamp to stdout?

         former to obtain the latter, and there are very
         good reasons not to."
