kj, you extended the context far beyond an addition to the numbering schemes available for reports in the Publishing workspace. My impression is that some of your feedback is a general caution to the community to avoid using a relative numbering systems in a non-relative situations. I agree. Of course.
I think the value of using numbering systems on reports and charts is self-evident. In fact, you don't even have the option to remove them on a number of FRM reports, and you'd lose a great deal of sensible organization without them. The question is about having the option to use the Ancestral Lines numbering system on these same reports and charts in FTM. Is, in fact, Ancestral Lines intuitive enough for those consuming the data?
I personally like its focus on numbering individual lines. This is information that Ahnentafel doesn't convey. I also like how the generation number is paired with the lines. That's intuitive and something that must be calculated with Ahnentafel numbering. On the other hand, when you get into a few generations and use the variation for siblings and pairings, I think it becomes too esoteric. It would need an explanation key to accompany it.
Anyway, it's got some good points and bad points. I'm just curious if others would use it over Ahnentafel if given a choice in FTM.
