Exactly. With Voyager contacting the Alpha Quadrant they had the chance to do something really spectacular.
It's not as if Message in a Bottle is the last episode of the series, there are 3.5 seasons left to go. Plenty of time to do something that you would consider "spectacular". And I don't want to spoil anything, but since you keep bringing it up, this will not be the last time they contact the Alpha Quadrant, not by a long-shot.
