Comment (by kaygee79):

 If I run the following code in WP 6.7.1

 {{{#!php
 <?php
 add_filter('wp_feed_cache_transient_lifetime', function() {
     return 600;
 });

 add_action('init', function () {
   $feed_url = 'https://news.un.org/feed/subscribe/en/news/all/rss.xml';
   $feed = fetch_feed($feed_url);
 });
 }}}

 I see an HTTP API request in Query monitor on every load, as well as the
 transient being updated:

 When I run the same code in WP 6.6.2 I see the initial request:

 [[Image(https://cdn-std.droplr.net/files/acc_1201575/VMIVB1)]]

 And as expected, I do not see any HTTP API requests on subsequent loads
 for 10 minutes:
