I'm thinking from the view of libgpiod or similar apps that abstract this and they will be "I want to use hardware timestamps if and only if it is available, otherwise I want to use this other timestamp" or is that use case uncommon, such that either you know exactly what you want or you should not be messing with hardware timestamps?
