Q1 is mapping on lookup permanent or transitional?

[Mark Davis]

Our meeting consensus was to forbid mapping on registration, require on
lookup, and discourage stored M-Labels.

For unmappable disallowed characters, I think it works fine to have a
transition period. But for lookup mapping I don't see any plausible way for
a transition period to end. So I think we end up having a permanent,
required lookup mapping.
