Why user-scalable=no, minimum-scale=1.0, maximum-scale=1.0 removed from viewport meta tag in Drupal Core

These value are mandatory in meta tags for responsive

Before:
<meta name="viewport" content="width=device-width, initial-scale=1.0, user-scalable=no, minimum-scale=1.0, maximum-scale=1.0">

Now:
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
