Review Comment:
Side question: Is there a difference between emitting a `null` value for a
dimension and just not emitting it? If not, maybe event builder itself should
have this null check.

Review Comment:
This seems a bit overkill and would add an extra serde step on completion of
every task action.
Should we expose a `getType()` method on the TaskAction instead or maybe
emit the class name as the type (similar to coordinator duty dimension in
`coordinator/run/time`)?
