This is fine when we're going to Create an organization, and in the process, many configurations will be saved in the SiteConfiguration objects, using those sites. If you change your LMS_HOST, CMS_HOST, etc, and run the settheme command, only new site objects will be created, but no new config created (or old configs` sites updated to use the new site objects).

When creating an organization, various configurations are saved in the SiteConfiguration objects (like "ENABLE_PROFILE_MICROFRONTEND": "true") and applied to the sites. If you modify LMS_HOST, CMS_HOST, etc., and execute the settheme command, new site objects will be created. However, no new configurations will be created, and the old configurations' sites will not be updated to use the new site objects.
