[whatwg] Proposal for Web Storage expiration

Yes, for IndexDB I think having a per-storage area expiration date completely makes sense. Do you expect that IndexedDB will become a successor to sessionStorage/localStorage? My belief is that the simple key-value store paradigm would still end up being the default client-side data storage utility, and would therefore benefit from having a per-key expiration time to mimic cookie usage.
To be clear, I think there should be expiration for all forms of client-side data storage, and adding it to one doesn't seem like a reason to not add it to all.

If we add this to IndexedDB then there are certainly multiple storage
areas. You can have any number of objectStores inside any number of

Whether or not cookies are a good model to follow, the expiration functionality is what makes auth sequences using them feasible.

If we add expiration to IndexedDB on an objectStore level, then the
page author doesn't need to do anything beyond setting an expiration
