Fwiw I think this is the right approach. The trade-off between stability across OS updates vs tracking performance is a no-brainer for me - the absolute last thing that I would want is a deluge of bug reports with no other information than "it stopped working" when Apple pushes out an update
As a developer I would interpret that as "try it in the new OS and you will immediately see what is wrong so there is no reason for me to write a tedious and unnecessary message to you".
