I think that the goal of "finding source of disturbance" interface

different from what can be accomplished by tracing in two ways:

category of event and it cause as opposed to determining all
precise
details about things being called that resulted or could result in
disturbance. It should not depend on the user's knowledge about
details
Tracepoints already give you selectively useful information.
Carefully placed tracepoints also can give the user information about
failures of open(), write(), execve() or mmap(). However syscalls still
provide an error code instead of returning generic failure and letting
user debug the cause.
