It is that way for a lot of "conversational" NPCs. Their scripts have never been created. I once made scripts for every single type of NPC and gave them over to Hal, but nothing ever became of them.
No, I understand you guys do a LOT of work to keep this running. Now I know at least it's not like there's something wrong with my NPC. I can live with it :).

Hal has not the authority, responsibility, nor ability to do anything about NPC scripts. Hal forwarded them off to somebody (don't even recall who, now) and promptly forgot about them. Hal probably has the file in his e-mail still, and might find time to throw it up on the Dev Wiki where it can be more widely viewed.
