PIN codes in the connection data are deprecated because PINs are
specific to the SIM card, not to the connection.  If you lose your SIM
and get another from the same provider, the PIN will be different, and
the PIN in the connection data will be wrong.  I've written up some
notes on what I think should be done in the GNOME bug report for this
issue:

Happy to help if there are more questions.
