Comment (by rishabhwp):

 == Reproduction Report

 === Description
 This report validates whether the issue described above can be reproduced.
 The issue concerns the ability to save an empty **Site Title** (also known
 as Blog Name) without any validation or user warning.

 === Environment

 * WordPress: 6.9-alpha-60093-src
 * PHP: 8.2.28
 * Server: nginx/1.27.5
 * Database: mysqli (Server: 8.4.5 / Client: mysqlnd 8.2.28)
 * Browser: Chrome 137.0.0.0
 * OS: macOS
 * Theme: Twenty Twenty-One 2.5
 * MU Plugins: None activated

 === Actual Results

 1. Navigated to **Settings → General**
 2. Cleared the **Site Title** field
 3. Clicked **Save Changes**
 4. The form saved without any error or warning
 5. The Site Title remained empty after saving
 6. No frontend or admin notices were displayed
 7. The same behavior was confirmed via **Appearance → Customize → Site
 Identity**

 === Additional Notes

 * This behavior can negatively impact SEO, accessibility, and theme
 rendering
 * Themes often use `bloginfo( 'name' )` for document titles, headers, and
 screen reader landmarks — its absence may cause rendering gaps or a11y
 issues
 * The **Tagline** field includes helper text, but the **Site Title** field
 does not, which may contribute to user confusion

 === Supplemental Artifacts

 * Video demonstration:
