Comment (by sabernhardt):

 I think the Site Title should be required **only** when creating a site.
 Multisite already does that in two places, but single-site installations
 do not.

 If you edit //other// settings in an old site, and receive an error about
 a new requirement, that experience would be quite unpleasant.

 I have needed to add a missing Site Title for someone, but I disagree that
 it is necessary for 100% of WordPress sites. Using a block theme, setting
 a static front page, and/or disabling feeds could mitigate at least most
 of the related problems.

 Also, the admin toolbar has had a [https://github.com/WordPress/wordpress-
 develop/blob/6.8.1/src/wp-includes/admin-bar.php#L377-L381 fallback] since
 #18197, which shows the domain.

 ----

 Single-site installations
 - `install.php`: does not require a site title to create a new site

 Any individual sites (either single-site or each site within a network)
 - Customizer → Site Identity: you can publish changes with an empty Site
 Title field
 - Site Title block: has "Write site title..." placeholder, but you can
 save with the block empty
 - `wp-admin/options-general.php`: you can save with empty Site Title
 - `wp-admin/options.php`: you can empty `blogname`, but the page clearly
 warns that "You can break things here."

 Multisite
 - `wp-signup.php`: requires title for new site in network
 - `wp-admin/network/site-new.php`: requires title for new site
 - `wp-admin/network/site-settings.php`: you can empty the `blogname` field
