There is still NO primer in the paint, never has been, never will be.

I think whether or not there is primer in the paint or not, this is not relevant. Also, the shadows and/or flashing is also not relevant. You will be putting new paint on areas that have been painted a year ago. This is usually enough to cause problems with touching up. Generally, flat paint touches up the best and the more shiny your paint is, the harder touch ups are. Darker colors are harder to touch up than light ones. Areas with light coming in from windows will be hard to touch up as well. Really, what most builders I know do is they tell the customers that they are free to choose washable paints, but touching up after the year end warranty work may be a challenge.

You don't need a primer though. You just need to apply two coats of paint to the repairs because the patches are porous. The primer being in the paint is just another way for paint companies to say that the paint is self priming or that using a primer is just not necessary.

exactly, which also means there is no primer in the paint :-)

I suspect there isn't any primer in the paint too. But, I'm not a paint chemist so I don't know what they are putting in there. My point is that even if they are putting primer in there, that doesn't help with anything or do anything. It's just a tool to trick people that don't know paint into thinking they are saving a step. Primer in the paint or not, you still need to apply two coats of paint over a patch.

If you ignore the hippy chick, this article explains it pretty well
