 Hello.

 Here's the context:
 I'm trying to write some high quality plugins that go through some code
 analysis tools before any new release is made available to the public.
 That means that the code that is being analysed is on a repository of its
 own.

 When running the plugin code through such tools (sensio labs insights for
 example), some errors are marked as major issues: "Global variable or
 function should never be used" and that is related to the access of some
 WordPress objects like $blog_id, $wpdb and $wp_filesystem to name a few.

 Upon investigation I found out that for $blog_id, there was an
 alternative, which is to use the get_current_blog_id() function. That is
 great, because it respects the WordPress way of working on the WordPress
 side, and in my plugin, I can now use a function instead of a global
 variable.

 Could we make some equivalent functions for the other global WordPress
 objects? Like get_wp_db(), get_wp_filesystem() for example?

 Thanking you.

 Regards.
