@skynavga Pointer to the WG resolution/decision here please? I do not think we need to mention ITU regions - it is up to the implementer to understand which regional preferences apply and therefore whether or not to implement this behaviour. Appending to the version of the text in this pull request something like "This behaviour is preferred in some regions." would be adequate.

is up to the implementer to understand which regional preferences apply and therefore whether or not to implement this behaviour.

Moreover, smooth transitions are not applicable to all transitions and all circumstances.
