Atm, the naming used in the Address class is incorrect. It uses encoded when should be raw, raw when encoded plus the name "plain". https://github.com/symbol/symbol-sdk-typescript-javascript/blob/main/src/model/account/Address.ts The trick would be to keep the old methods with a deprecated annotation to not be a breaking change. The rename should follow the standards in the docs https://github.com/symbol/symbol-docs/pull/682
