Providing a conversation function is not an issue (although there might be
some uncertainties, as how it should behave if a module explicitly
requested PAM_PROMPT_ECHO_ON).

My point was that the same conversation function can be used for chpasswd,
newusers, and passwd (i.e. I did not agree to "...but instead of all the
quirks to get the encrypted password back from pam...")

Once chpasswd supports PAM, do you still need passwd --stdin?

Supporting PAM in chpasswd looks much easier than supporting
non-interactive password updates in passwd. (mostly because of the non-PAM
paths)
