 I'd advocate for a short-lived cache (e.g. 30 seconds).  There are several
 scenarios where this page could be requested multiple times in a short
 span.

 Consider clients that pre-fetch content, or re-fetch content (extensions,
 scripts).  Or possibly a plugin mistake that contains a self-reference
 error (example below) that would cause the browser to fetch the same URL
 again:

   `add_action( 'admin_notices', function() {echo '<img src="?" />';} );`

 This may easily save some traffic for api.wordpress.org in some edge
 cases.
