That's true. Although right now TMF doesn't have an API to ask a trace
"give me all the event types you have", other than just reading the
wrt CTF, it's possible to have events in the metadata that don't
actually show up in the trace. But that's not really a problem, at worst
you'd end up with empty columns.
