Safari ITP 2.3: Capped Lifetime For All Script-Writeable Website Data

I am a little confused about Safari's ITP 2.3 policy which caps the lifetime of script-writable storage in the browser to 7 days.

The official article states that:

After seven days of Safari use without the user interacting with a web page on website.example, all of website.example’s non-cookie website data is deleted.

This definitely includes localStorage. Does someone know for sure whether

• IndexedDB
• CacheStorage
• Service Worker

are cleared as well?

Looking at the relevant Webkit commit, it clearly includes IndexedDB - it does not seem to include CacheStorage or ServiceWorker.
