Is this a regression?
i'm not sure
Description
when i export a component in the library module but not in the public API
the build command throw errors only in normal mode, but in production mode it completes successfully
🔬 Minimal Reproduction
clone https://github.com/robertIsaac/test-library
and run ng b and ng b --prod
or generate from scratch
ng new test-library --create-application=false
cd test-library
ng generate library test-library
ng g c test-export --export
ng b
ng b --prod
🔥 Exception or Error
both commands should throw the following error
Unsupported private class TestExportComponent. This class is visible to consumers via TestLibraryModule -> TestExportComponent, but is not exported from the top-level library entrypoint.

Anything else relevant?
it would be nice if --export command also update the public api file if it's running inside a library

@robertIsaac, the problem here is that the above is only an error when using Ivy rendering engine, with View Engine which is used for production builds, this is valid.
That said, we should add the export to the public api when using the schematics so that we generate valid code for both rendering engines.

Do we need to add all exports in public.api.ts or any other work around after angular 12.
