I'm not sure what the acronym CIB stands for or what the discussion there was, so can't comment. But, in my humble opinion only, "because we don't have time to work them all" isn't a reason not to find them. In fact, counting the scope of the profiles impacted could be a reason to spend more resources in finding an automated solution.
Plus, you never know when someone new will join who feels passionate about adding that information and will pick up the torch.
For example, if Ales can somehow figure out how to accurately match up the cemetery on the FindAGrave link to an existing category, then I suppose he could probably just have EditBot fix it on the WikiTree profile. But, if it's only 1,000 or even 10,000 that might not be worth his time. If it's 10,000,000, then it might be time well spent. That's above my pay grade.
And as Stephen suggested, I would have no argument with opt-in, adding it to profile completeness would do that nicely. Already on my to-do list for profiles I manage anyway, just haven't got to it yet.
Good discussion, all! Learn something new everyday.
