IMHO the 1000' landing config rule is utter tosh. It is absolutely no problem (on the boeing) to select the last stage of flaps at or even slightly below 1000' and be fully stable at 500RA.
This is the reason why ezy cannot do 160 until 4dme, unless you want to stress the flaps.
In my view doing a go-around at 1000' because the flaps are still moving is total fuel wastage!
We are not challenged to squeeze performance from the aircraft. We are challenged to achieve precision in flying the aircraft as closely to the OM as conditions allow. The OM is crafted to balance both economy and risk management. Perhaps its a slow creep of procedural ‘disregard’ born of years of successful flying. We are so good at flying the aircraft that we are slipping on the standard of precision required. Pilots who have become so confident in their ability to fly the line that they feel empowered to interpret the OM based on their experience level instead of the word and intention of the SOP. It is both possible and desirable to fly "by the book" every day.
