<li><a href="https://profiles.wordpress.org/weston/" class="mention"><span class="mentions-prefix">@</span>weston</a> has been working on adding async/defer to more places in core
<ul>
<li>Merged <a href="https://github.com/WordPress/gutenberg/pull/52536">this PR</a> that used defer for all block view scripts</li>
<li><a href="https://core.trac.wordpress.org/changeset/56323">Committed</a> the use of <code>async</code> for the <code>comment-reply</code> script in core</li>
<li><a href="https://core.trac.wordpress.org/ticket/58931">Proposed</a> adding <code>defer</code> to the <code>wp-embed</code> script, even though <a href="https://core.trac.wordpress.org/ticket/58931#comment:3">his analysis </a>didn’t show much performance benefit.</li>
</ul>
</li>
<li><a href="https://profiles.wordpress.org/weston/" class="mention"><span class="mentions-prefix">@</span>weston</a> reported that now that HTTP Archive has <a rel="noreferrer noopener" href="https://github.com/HTTPArchive/custom-metrics/pull/85" target="_blank">custom metrics for WordPress scripts</a>, he’s been starting to dive into doing queries for how well sites are using the scripts API, including to what degree they’re using <code>$in_footer</code> and how many are currently using <code>async</code> and <code>defer</code> even before our official way of doing so</li>
<li>He’s also been doing some research into which specific plugins are responsible for those <code>blocking_in_head</code> scripts. So we’ll have some opportunities for ecosystem outreach hopefully soon</li>
<li>Review/feedback on his HTTP Archive queries would be appreciated
<ul>
<li>Later in the meeting, Weston followed up to share that Felix had identified a flaw in the query he was using go get counts of scripts using <code>async</code> and <code>defer</code> from the HTTP Archive. He plans to revise and share updated results</li>
