I'm not sure I understand the sync script bit.
You don't want to block user interaction with the page while fetching
a <script>. You also don't want to block the parser tokenization
prescan, preloads from that prescan, etc.
All that should be blocked is DOM construction from the parser.
We're probably blocking too much right now. We'll need some follow-up
work to optimize this, and also to make it use the correct fetch
algorithm and support async/defer.
