Maybe not, because the need for an elaborate
classification is strongest in the case of semeai.
The KO_A/KO_B scheme seems be adequate for ordinary
owl reading, where there is only one group in
question.

In GNU Go 3.4 there was a field semeai_margin_of_safety
in the dragon2 data. The field was taken down at some
point because the measure was never really implemented,
but the idea was to have a parameter indicating how
close the semeai was. I think there could be some
scheme in which this parameter would used in connection
with the KO_A/KO_B results to classify yose kos.
