Comment (by hellofromTonya):

 In that line of thinking:

 What if there is a real-world use case for `WP_CONTENT_DIR .
 '/themes/functions.php'` to exist? If there is, then returning empty
 strings from `wp_get_active_and_valid_themes()` would break loading that
 file on those sites.

 What are the other impacts of real-world usages of invoking
 ``wp_get_active_and_valid_themes()` when `get_stylesheet()` and/or
 `get_template()` return an empty string?

 Is `wp_get_active_and_valid_themes()` intentionally designed to allow only
 pointing at the main themes directory (root)? Or is this an oversight? hmm

 I'm curious of the potential BC breaks of such a change.
