I don't think the window indexing is really intended to provide venting to make it easier to close the doors. The purpose of indexing is to lower the windows just enough to clear the groove they seal in at the edge of the roof, then raise the window into that groove after the door is closed.

It is done to get a better seal and reduce wind noise. Tadge said at a "Bash" when asked why they didn't just lower the windows more to help the hatch latch, said they are only allowed a 1/4 inch to avoid pinching. I assume he was referring to a child's nose/hands (and dog's as well) getting pinched when the windows would automatically close after the hatch latched. In a later GM bulletin re dealer testing hatch closing, it said to open both windows 2 inches! Probably what is needed to make the doors easier to close as well. Could easily check for those with hard to close doors to see how much that helps.

after living with the car for another day or so, I find that after indexing the windows, the doors still need a little extra force to close properly.
Will likely just involve developing proper muscle memory.

Mine lowers a little, but it is not enough to release the glass from the seal. My Driver's door is a bear and I typically pop the hatch when getting out and then shut the door.. Then I go back and lightly push on the rear hatch to let the auto-latch lock it. Pain at this point, but it has been in the garage because of the weather...

To call this a problem is a little silly. You just have to pull the door a little harder than say in a C6. Big ******* deal.

My C6 coupe's doors close very easy, and I don't get any water intrusion nor do I have any wind noise at 160+ MPH.
Just sounds like the windows are adjusted where they tilt in a little too much at the top. Maybe a simple window adjustment is all that is needed.

Mine is a coupe, and I do believe from all the posts that a soft top allows the doors to close much easier. But I have now indexed both windows, and the doors are a bit easier to close than before, but still harder to close than on my 2010. I can live with that, at least until something needs replacing.

This door closing issue is not unique to the 2016 Coups. I have the same problem with my 16 Vert.
When you close it from the outside you can see the indexing is working but it simply does not open far enough to clear the seal. This needs to be fixed by GM in the software. Obviously not a problem with the top down.

I wonder if this is a side-effect of getting rid of the vent in the rear. Fixing the hatch closing issue while creating a door closing issue.
More reasons to buy a 'vert. No problem closing the trunk or doors.
When I slam the door, I can see the bottom edge of the roof lift slightly to release the pressure.
