@clayinho - I think the pivot effect of using only 2 mounting points is the main concern. Adding 2 more mounting points from the rear most d-rings would eliminate that potential issue. Even though you found 2 mounting points strong enough previously, adding 2 more at this stage seems like a pretty simple addition for a fairly minimal amount of effort. But it's obviously your decision to make; I tend to err on the side of caution on this sort of thing.
I'd love to read about how you created the template to use for tracing the cut onto the plywood and how you went about finding the correct place to drill the holes for the mounting points.
In my case with a 2020 HE (no 3rd row seats), I don't believe I have the 3rd row seat mounting points available to use, which I restricts me to using the 4 d-ring mounting points unless I want to start drilling holes in the floor (I would prefer not to). If I could find a bolt with a low profile head that also has enough strength, using 4 of them on the d-ring mounts with fender washers would probably be the solution I would go with and not worry about a recessed mount to avoid weakening the plywood. If drawers are being installed, a flush mount isn't super important anyway as long as the bolts don't stick up high enough to interfere with them.
