It'll be bit awkward that EventName gets exported automatically, but EventId still requires opt-in. But still, I think that is the way forward.

@Kielek Not before the next stable release. This was not a part of the earlier code. I see you had created an issue to track this item; we could add it after this stable release.

Adding EventName can be a separate PR if we chose to add it.
