I don't get what the significance is. Darla was also invited and it has no significance beyond the episode where she was invited. Whatever happens Seasons down the line doesn't mean much, as you can't use future story lines (which they made up anyway especially in regards to Spike) to defend the past and attribute significance to it. When it happened it was all about pragmatism, with no thought of the future.
