Comment (by jeremyfelt):

 Thanks for exploring this, @flixos90.

 > However, there are several functions that return a "site-like" object on
 non-multisite installs as well.

 Can you highlight some others beyond `get_blogs_of_user()`? I can somewhat
 see some of the benefits there, but can also see reasons/ways around them
 (I think). I didn't look too closely elsewhere, but it would be helpful to
 have other examples for context.

 In general - I'm wary of pushing for `WP_Site` to exist outside of
 multisite in the near future due to its close relationship with the
 `wp_blogs` table as well as a handful of its properties that only
 multisite understands. Of course, it's always possible that this changes
 in the future. :)
