OK, that's one thing; another is that it'll be the same REPLY event.

I don't recommend your patch because the original reasoning might've
been that a REPLY event isn't significant enough to be 'saved' anywhere.
It might be better to use your _adaptation_ instead.

Otherwise the 'right' way to do this would be another method for the
REPLY event.

(cl-defmethod gnus-icalendar-event:sync-to-org ((event
gnus-icalendar-event-reply) _reply-status) ...)
