Comment (by Denis-de-Bernardy):

 Slightly off topic, but since the ticket mentions "cleanup of multisite
 load" in its title: there's a lot of code in wp-includes/ms-*.php that run
 very early and assumes that WP is already installed. When it isn't and
 you're hoping to get redirected to wp-admin/install.php, it ultimately
 fails with an extremely misleading database connection error.

 Would it be desirable (in a separate ticket, of course) to make so that
 adding the relevant multisite defines in advance, when installing WP,
 would make the installer just work and set things up with multisite
 already up and running? Desirable or not, I raised the question here
 because a few `isset()` calls here and there are currently needed to avoid
 E_NOTICE errors when loading `wp-admin/install.php`, so might as well add
 them in advance during the cleanup.
