I think the only variant on this bug worth any more chatting about is that if you completely take away the PAPI issue he’s also saying that the ILS glidescope puts you too high over the threshold as well, so it’s basically two separate bugs. It sort of gets into the weeds a bit as the issue then is that the RA shows 70 when it should be 50 feet, and then all sorts of details of if that’s meant to be the bottom of the wheels or the cabin height. At that position it will mean things do go long for the 1000 zone usually. If you just fly 5 seaters it is probably never noticeable. I’m not a SME in this, but I guess it could be a bug in itself and more repeatable reports would need to come. 737NG seems fairly convinced anyway, but there’s no bug report for it as it stands I don’t think.
