Any experts in acs-relationships and all that crud out there who can help me with some of the details on that? It would seem to me that that would be the right way to model relationship between bugs (duplicate, depends on/blocks, just related, ...), user interest/"notify me", mapping tickets with patches, assignments, maybe even mapping bt_code_values to bt_tickets.
Any comments on that assumption? Is that the right way? Will it perform? Will it be more trouble than it's worth? Any implementation hints?
