Are we going to do that hard-coded special casing work every time a little change is made?

4. Registries inform the registrants and offer a grandfathering registration (like the .mx registry recently did) that allows all registrants of domain names with ss to register the ß sibling if they like.

That would be good, but registries aren't all TLD, nor are they all consistent.

Like *some* humans do, which is part of the problem.  My year in a Bitburg Grundschule was prior to the spelling reform and I see very little distinction, though my limited preference it toward the "correct" spelling.  Swiss probably have a similar attitude though likely with somewhat different biases.
