I agree, password.el was only something that might go in when we
aren't in a feature freeze. I have backed out the change.
Since password.el will be used by Gnus CVS, our discussion haven't
been in vain, though, since I will incorporate some of the ideas
discussed here.

It was added later on, not by me. I suppose he who added it might
argue that it is useful, though. I tend to think that there should
only be one worked out interface. (I'm not saying the current API,
without p-r-a-a is the best interface, only that it would be better
with only one interface.)

I think so too.

Perhaps the experience with how password.el is used in Gnus CVS will
help in sorting things out.
Thanks.
