What kind of notice could/would/will we expect?
I've got coins spread across various devices, forms of storage etc. I don't fancy being left with a load of shitcoins (whichever becomes the defeated chain).
It's only an issue for coins stored on keys you don't control (exchanges primarily)
Though it could get kind-of complicated for regular coins if a fork happens and the weaker fork somehow manages to stay relevant for any period of time.
