Yes, and? That’s a boil the ocean solution. Every app and site needs to look up urls and update where as they didn’t before.

Most apps and sites will have a thumbnail for the site. So they're already loading the page.

Other sites grab contact information or verification headers. So they also load the page.

Seems like the only people who wouldn't want to load at all, would be those places where deduplication doesn't matter in the first place.
