Google is allowing users to change their Gmail address, per official Google support doc — experimental @gmail feature rolling out in India first, no official announcement yet

Google is introducing a new feature that allows users to change their Gmail addresses, a departure from the long-standing restriction on altering @gmail addresses. The feature is currently rolling out in India first, as indicated by an official Google support document in Hindi. Users will retain access to their old email address even after switching to a new one, essentially enabling them to have two @gmail addresses for one account. While the global rollout has not been officially announced, users can check for the option to change their email address in their Google Account settings.
