>These events can also be used to easily trace raw tracepoints that lack a trace-event declaration. Raw tracepoints were created to make it harder to get at deeply internal kernel features, thus making it less likely that user space would come to rely on them; fprobe events are now making it easier again.

It's not easy enough for an application to rely on it. There's nothing that exposes the tracepoint that you want to connect to. You have to read the code to see if it exists or not. It's no different than adding a kprobe trace to a function.
