Before considering a hard fork with unpredictable effects on the
uncertainty window, it would be interesting to look at a soft fork that
would directly target the goal of reducing the uncertainty window, like
treating locally-detected double-spends aged > T as invalid (see earlier

If anything is worth a soft fork, wouldn't reducing the double-spend
uncertainty window by an order of magnitude be in the running?
Reducing the reasons that transactions don't get relayed, which actually
seems to have a shot of happening pretty soon, would also make this kind
of thing work better.
