This feature has received a negative standards position from at least one browser vendor — It's very unlikely to ever become Baseline in this current form.

The sharedStorage API stores data to a shared space where the data can then be processed without the ability to track users across the different sites they visit. A common use case is measuring the reach of third-party ads without using user-tracking cookies.
