Why do so many cars require you to manually open the front door to unlock the back doors with Passive Keyless Entry?

I have a 2017 Acura, and in order to unlock the rear passenger side door I have to physically pull the handle on the driver‘s door. This doesn’t really make sense from a design standpoint, considering people very often need to put stuff in the backseat before getting in the driver’s seat. If I had children, I would be even more irritated by this oversight. Something that was corrected in later models?/
