Once the registries (of that support the 4 special characters) have adopted
bundling/blocking policies, then it will be possible for client software to
safely move off of the transitional approach. So it is really dependent on
the registries' behavior. Different clients may have different thresholds
for when to move, depending on their estimation of when enough important
registries have adopted bundling/blocking policies.

exclusively support IDNA2008

"All client software" doesn't work, unless you have a coordinate switch
date, which people concluded was impractical.
