At least from my experience writing an AMF integration for another software and testing with current hardware, older Drivers work just fine. If necessary I can port the entire compatibility structures I built for another open source software to FFmpeg, which would extend the minimum driver version to 19.7.1 and would include drivers that cause stack and heap corruptions, weird dlopen/LoadLibrary issues, and more. If you meant compatibility with older versions of the SDK, it is possible. Since this is meant to add new features, increasing the minimum SDK version felt line the better choice than allowing users to build amfenc "wrong" and getting a completely different set of options out of FFmpeg.
