BREAKING CHANGE: Removal of View Engine support from i18n extraction
With the removal of the deprecated View Engine compiler in Angular version 12 for applications, the
ng extract-i18ncommand will now always use the Ivy compiler. The--ivyoption has also been removed as Ivy-based extraction is always enabled.The default behavior for applications is to use the Ivy compiler for building/extraction and no changes are required for these applications. For applications that have opted-out of Ivy, a warning will be shown and Ivy-based extraction will be attempted. If the extraction fails, the application may need to be updated to become Ivy compatible.
