It's not obviously clear that having this be a default is in the user's best interest.

e.g. For IndexedDB that does support this, it's only supported when the user has explicitly allowed it.

Also, if we did implement persistent storage of partitioning for localStorage, it would almost certainly fall under the same umbrella of "only if the user explicitly allows it"

Can you better describe the mechanism by which 3rd parties store persistent data on the first party?

Knowing details will better help analyzing the tradeoffs between the current state of things and implementing the proposal.
