This is such a fun idea! Definitely going to try this next time I’m on a large enough team / teams, for a bit of holiday fun. I imagine it’s kinda silly with 4 people.
I just said look I can't figure it out. I tried but I couldn't do it. If someone else wants to try, please be my guest and told the team I was removing my name from the ticket.
I can see it being useful any time there are issues nobody wants to handle. Backlog grooming seems to stand out as a prime use case.
