What the author says it does
This plugin’s purpose is to optimize the performance of embeds in WordPress, such as Tweets, YouTube videos, TikToks, and others.
The current optimizations include:
- Lazy loading embeds just before they come into view.
- Adding dns-prefetch links for embeds in the initial viewport.
- Reserving space for embeds that resize to reduce layout shifting.
Lazy loading embeds improves performance because embeds are generally very resource-intensive, so lazy loading them ensures that they don’t compete with resources when the page is loading. Lazy loading of IFRAME-based embeds is handled simply by adding the loading=lazy attribute. Lazy loading embeds that include SCRIPT tags is handled by using an Intersection Observer to watch for when the embed’s FIGURE container is going to enter the viewport, and then it dynamically inserts the SCRIPT tag.

Read from the WordPress.org plugin API on , when WordPress 7.1.4 was the current release. WordPress.org rounds active installs into buckets. These are the directory's figures, not my verdict, and I haven't tested this plugin.
