The user doesn't know whether the lower level tapset has marked a binding as
optional or not. Thus, when the user writes a probe on syscall.foobar, they
will likely be surprised if this probe was automatically removed. We should
avoid surprising results.
At a minimum this should be an warning, but I still think it's better to be an
error.
