Currently site name, etc. gets version controlled, which (of course) isn't appropriate. We want sensible defaults instead and an install-time mechanism for overriding them.
Implement this as a 'config/local.default', which gets version controlled. The contents of that should be copied over to 'config/local' and edited/imported as appropriate. (There are corresponding 'site.default' and 'site' config split settings that get switched off/on in 'settings.local.php' prior to import.)
