As it contains code referencing solidus_frontend, we need to move it to the [solidus_frontend installer](https://github.com/solidusio/solidus_frontend/blob/master/lib/generators/solidus_frontend/install/install_generator.rb).

Sure, @piyushswain. Sorry for not being clear enough. Since https://github.com/solidusio/solidus/pull/4490, the Solidus installer prompts the user to select [solidus_frontend](https://github.com/solidusio/solidus_frontend) or [solidus_starter_frontend](https://github.com/solidusio/solidus_starter_frontend) as storefront.

Hey @RyanofWoods, after talking with the core team, @spaghetticode came up with an idea that we think could solve the concern about breaking tests. What about modifying the address factory...

Hey, @RyanofWoods! :wave: Did you find the time to think about the proposed solution? Do you think it's something that makes sense?

Thanks, @BenMorganIO! Do you think it'd make sense to use the already available [`.checkout_zone` preference](https://github.com/solidusio/solidus/blob/b4ff5ce951654ff070878da6a4ca7fba4418f135/core/lib/spree/app_configuration.rb#L121). Having another `.available_countries` setting is redundant.

I already merged the one for 2.10. As I think it's the only one needed, I'm going to close it. Thanks for working on it!

Oh, I just saw a PR for 2.9. Reopening!!
