Specification
We’re actively working on adding the relevant spec concepts with
the following WIP PRs (there has been some extensive refactoring
requested, so it’s taken longer than anticipated):
https://github.com/whatwg/html/pull/8447

Summary
We intend to partition a number of APIs in third-party contexts.
This effort is focused on partitioning APIs above the network
stack. This includes quota-managed storage, service workers, and
communication APIs (such as BroadcastChannel). See the explainer
for more details:

WebView application risks
Does this intent deprecate or change behavior of existing APIs,
such that it has potentially high risk for Android WebView-based
applications?
We’re still investigating the risk for WebView, and if we should
ship in that context at a later date.
Goals for Deprecation Trial
We propose to ship two separate deprecation trials, each for
approximately one year (to give sites plenty of time to test and
update, if needed). Aspirationally, we would like to ship
partitioned storage in M112, and our goal is to have a deprecation
trial available from M111 to M123.
The first
<https://bugs.chromium.org/p/chromium/issues/detail?id=1404959>is
a general-purpose deprecation trial that will allow a top-level
site to opt into unpartitioned storage, service workers, and
communication APIs for third-party contexts embedded in its site.
This will give sites more time for testing and migrating to
solutions that don’t require partitioned storage.
The second
<https://bugs.chromium.org/p/chromium/issues/detail?id=1399319>is
tailored to a behavior we discovered during the dev-trial that is
known to be used by the Firebase Auth library. This deprecation
trial only allows for unpartitioned `sessionStorage` across a
navigation (which is how the `signInWithRedirect()` method relies
on storing and postMessage’ing authentication tokens). The
Firebase team is aware of the issue (as it also affects Safari
users; Firefox has worked around the breakage by granting
unpartitioned storage via a shim
<https://github.com/mozilla-extensions/webcompat-addon/blob/f58cf9e13b088fde01a0551069d23862e71e6711/src/data/shims.js#L791-L801>),
and is working to migrate their users
<https://firebase.google.com/docs/auth/web/redirect-best-practices>to
cross-browser solutions that are compatible with partitioned
storage. Given the different nature of the Firebase issue, we
think it makes sense to ship a different deprecation trial entirely.
Debuggability
DevTools has support
<https://bugs.chromium.org/p/chromium/issues/detail?id=1296581>for
partitioned storage.
Will this feature be supported on all six Blink platforms
(Windows, Mac, Linux, Chrome OS, Android, and Android
WebView)?
Yes for all others; TBD for WebView.
Is this feature fully tested by web-platform-tests
<https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md>?
Yes
