I remember there were a couple of concerns:

(1) it also doesn't work with GnuPG2 at all (have you tested it?)
(2) even with libnettle, you need to implement OpenPGP packet handling
    if you want to keep the data compatibility with GPG (I don't think
    it is a good idea to reinvent another encrypted data format with
    plist as you proposed)

Even then, it is combersome for me to type "n" to proceed to the next
step (i.e. accessing smtp, etc).  Firefox allows user to keep browsing
password protected Web pages without answering the question immediately.

How about:

(1) add M-x auth-source-save command to save passwords manually
(2) (message "Type \\[auth-source-save] to save your passwords to file")
    instead of the question
