When saving and retrieving favicons we can likely ignore ref.
It's true that potentially the page could serve different content for different refs, but the use cases to provide different favicons is very limited, and it would make the site harder to recognize for users.
On my database this would save ~150KiB out of 70MiB.

Merging existing URLs may be nice, but it may not be necessary as the savings are not huge. Thus we could just start doing it for new entries.
