You definitely went over the top. Aaron had no idea that RO6-preview would not work on VRPC-Adjust until I was given a beta copy of RO6-preview to test and could not get it to boot. It was certainly not by design as you seem to imply.
Besides, as far as I know Aaron has never stated that users of earlier versions of VRPC would need to upgrade. Personally, I would either expect a fix for the affected versions of VRPC or for RO6 as soon as the reason for the incompatibility is known.
