Re point 3:  Today on Catholic radio I heard Radio Nun go on at length about how it was absolutely wrong to visit a relative who wasn't properly married.   More specifically, the question was from a mother who was seeking a way for her children to visit their Grandfather.    Absolutely out of the question! said Radio Nun.   You didn't break up the family, he did by choosing mortal sin, etc.

Where do Catholics get these ideas?  The catechism's chapter on scandal.

If Francis truly wants to be a reformer,  truly make the Church a place of welcome for all, then he needs to definitively amend that chapter.   But as things are now, he appears to want to leave that chapter in place as law, and kind of talk around it.
