A site manager has an intuitive way to leave site administration and view the site's home page, without extraneous options to log out
Background
"When i hover on [far left of admin menu on every page, the blue Drupal 8 Druplicon offers 'log out'] and i'm afraid i'll log out accidentally" — Drutopia member who administers Family & Home.
I would add that the Drupal 8 Druplicon icon doesn't indicate clearly that it takes you to the home page, or really that it does anything.
Proposed solution
Remove the 'logout' dropdown link, change the Druplicon to 'Home' or a house icon or to the site's favicon.
