site_url(), or home_url()?

I’ve just installed Custom Community 1.14 using automatic installation from the WP dashboard. I noticed that the URL where the blog title in the header is not the home url (where index.php is, e.g. https://example.com), but site url (where the wordpress core files are, e.g. https://example.com/wordpress).

After some quick tracing, it seems that all the calls to site_url(), in the function header_logo() (lines 196, 200, 205, and 208), in custom-community/core/includes/theme-generator/theme-generator.php, should have been home_url().

Is this a bug? Or is there some reason that site_url() is called instead?
