Or if the bookmarks plugin coild see the key counts on import/export, would that do it?

Syncing with one person mostly works because you have to go out of your way to modify information in multiple tabs at the same time. But, if you work at it, and watch carefully, say two windows open right next to each other, and star portals in one window, then immediately star one in another, you can see one disappear due to the race conditions.

Current implementations of syncing work on the collection level (bookmarks, keys, etc), not on the item level within any given collection.

Opening up sharing to multiple people, who might actually modify the same collection at the same time, it would likely increase the chances of losing data. And you're less likely to notice it than if you do it to yourself.

In short, a lot of work would have to be done to improve internals before even attempting this.
