Comment (by spacedmonkey):

 That doesn't make any sense. Adding to `WP_Network` means it can be called
 from any context. The magic getter should do the fallback lookup. I think
 where possible we should be using `BLOG_ID_CURRENT_SITE` and
 `BLOGID_CURRENT_SITE` where possible, as these do not require a lookup.

 Replying to [comment:15 flixos90]:
 > I agree that there should definitely be a magic getter for the main site
 ID of `WP_Network`. But the actual code should be part of
 `get_main_site()` so that it can be called independently. The magic getter
 could then call `get_main_site()`.
