Description

Implementation of storage shelf/bucket/bottle model in Storage Standard.

[annevk]

I discussed this with some colleagues and at the moment we're not entirely convinced this feature is carrying its weight. From WICG/storage-buckets#92 it does not seem like there is a lot of developer interest and per https://web.dev/persistent-storage/ eviction is already very rare. So building an entire system around optimizing for the rare case might be a bit much? Perhaps persistent storage is a good enough solution for that.

Offering expiration for storage makes sense though and is a feature we've seen demand for as well. But that cannot carry storage buckets on its own.

Anecdotally, one use case I have in mind concerns JWTs. Currently, those are cached in client-side storage and manually cleared when the front-end detects a logout. If they were stored in a storage bucket, I would be able to use Clear-Site-Data to clear specifically the JWT bucket from the server-side.
