The use of an enum value to define the size of an array is an unsual pattern which caught me by surprise.

It makes sense, but it's not commonly used, so I would add a comment to point it out.

Something like: "These arrays must be able to contain a value for each event kind. RMW_EVENT_INVALID is used because it is the last enumeration of rmw_event_type_t".
