Is this a regression?

We have an application with universal, where the app.server.module.ts file is not in app folder, when I tried to use ng generate appShell --appDir='path' it ignores it throws exception

Specified module 'app.server.module.ts' does not exist.
Looked in the following directories:
/src/app/app.server.module.ts
/src/app/app-shell
/src/app
/src
