That still puts you within the 6 milestones you can get for free - so,
LGTM to extend to 137.
If you truly want to stop at 136, you can do that too. But you've got an
extra milestone in case you need it.

Specification
https://wicg.github.io/document-isolation-policy
Summary
Document-Isolation-Policy allows a document to enable
crossOriginIsolation for itself, without having to deploy COOP or
COEP, and regardless of the crossOriginIsolation status of the page.
The policy is backed by process isolation. Additionally, the document
non-CORS cross-origin subresources will either be loaded without
credentials or will need to have a CORP header.

Risks
Interoperability and Compatibility
None
/Gecko/: No signal
(https://github.com/mozilla/standards-positions/issues/1074)
/WebKit/: No signal
(https://github.com/WebKit/standards-positions/issues/399)
/Web developers/: Positive
(https://github.com/WICG/proposals/issues/145) See the initial WICG
proposal. We've also been in touch with developers at Google and
Microsoft who think the proposed API will allow them to use
Shared-Array-Buffers.
/Other signals/:
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?
None
Goals for experimentation
Reason this experiment is being extended
Two crashes have been reported (crbug.com/394350439
<https://crbug.com/394350439> and crbug.com/393480086
<https://crbug.com/393480086>) which will force us to turn down the
experiment in M132 and M133. We would like to give enough time to
tester to report any additional issues, so we'd like to extend the
trial by 2 milestones.
Ongoing technical constraints
None.
Debuggability
None
Will this feature be supported on all six Blink platforms
(Windows, Mac, Linux, ChromeOS, Android, and Android WebView)?
No
Our Origin Trial will only be supported on Windows, Mac and Linux at
first, as support on Android requires more development work due to the
different process allocation model. We will add support on Android as
soon as possible. Support on Android WebView is not possible due to
the lack of process isolation.
Is this feature fully tested by web-platform-tests
<https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md>?
Yes
