I am actually reasonably sure it does? David Wu - katago creator took huge pains to implement proper Japanese rules. And KataGo would be the one scoring these cases.
I think we should track two things:
The scoring was rejected, and resumed (here 3 sounds like a good start)
How many times the board state was updated (For players who just click away any proposed state) Here I would go much higher like 20 updates maybe?
Even if it’s genuinely architecturally infeasible to “reverse” the Elo results of a finished game, you should be able to create hidden dummy games that yield the correct Elo point outcome.
