We have also laid some groundwork for the eventual transformation toward "OK, now you know, it's your turn to be Santa's hands for others" (spirit of giving etc.) Not so much "Santa doesn't exist," but "we keep the spirit of giving alive for one another in this way."

That's what we did with DS when he finally decided Santa wasn't real -- I told him that now he gets to BE Santa for his sister. I don't know what the heck I'll do with her, but she's the sort of imagination-heavy kid who will keep it real in her mind forever.
