Marvel stopped Spencer from dealing with OMD. Spencer never got to have anything resolved on Peter/MJ's side with Kindred, it was completely retooled last minute to be Norman's sins only. This was supposed to be about something Peter did and needed to confess to, Marvel stopped that. They don't want to have Peter admit that the deal anything he needs to "confess" or that it was wrong in any way.
Kindred went on and on and on about Peter's sin, the one that made Kindred into what he was. Peter MADE KINDRED according to ASM 55. That was retconned by editorial and it was Norman/Harry only who made Kindred.
There is no way they will get married again.
