As for the desire to avoid hurt feelings, some may consider it oversensitivity. There are two reasons for this new nomenclature: simplicity and the avoidance of hurt feelings. The Greek-letter labelling proposed by the WHO is therefore an official attempt to provide the convenience of simple, uncontroversial monikers. Currently, there are no plans on how to label the variants after the 24 letters of the Greek alphabet are used up. These old names are not abandoned.
