It seems I misunderstood how it worked, indeed. I thought the prompting
could also be done by the helper (it seems sensible if you're going to
use your desktop's keyring to also allow the desktop's GUI for prompting
for example).

Looking closely at the code, credential_fill either delegates fetching
data to the remote helper, or does the prompting. IOW, the prompting is
done behind the C API anyway, but most likely from credential.c than
from the external helper. Is that understanding correct?
