[Impact]

 * The system-users-symbolic icon doesn't represent users in the plural. It shows a single generic figure (head and shoulders) representing one user. This is a misleading visual metaphor, since a single head and shoulders is universally recognised as the current or logged-in user.

 * Reason to backport to Focal: the corresponding Adwaita icon shows two users. Third party apps that use the icon will expect it to represent more than one person. Failing to provide a suitable icon will have confusing results in Ubuntu.

[Test Case]

 * Install Lollypop and look at the sidebar. "Compilations" has the symbol of a single user, which is confusing. Lollypop requested an icon with multiple figures to represent multiple artists, but Ubuntu supplied something inappropriate. This issue may be duplicated whenever a third party app uses this icon.

 * Build Yaru from Master and notice how the icon now has the same visual metaphor as Adwaita (i.e., it shows two users). The Lollypop UI makes more sense and the theme honours the app's intentions.

[Regression Potential]

 * No regression potential.

 * Tested by building Yaru from source.
