Camille and I met yesterday to discuss this intent.
LGTM to extend to M146, contingent on the fact that we set up a renewal
flow that only allows renewals for existing participants. However,
Camille will be out for ~2 weeks, so let's extend this now on the
backend and set up the registration approval flow when she gets back (I
am happy to help, having done this once before). Another option would
also be to ask the OT team to close new registrations in ~2 weeks (this
may not be a supported workflow, dunno).

No unfortunately we did not do it at the time. Now it's clear we
really need to do it.
*Reason this experiment is being extended*
The release of DocumentIsolationPolicy in M137 is helping
developers adopt crossOriginIsolation as a way out of this
reverse Origin Trial. However, it will still take time for
developers to adopt. We would like to extend the OT as the
final extension and give developers 6 milestones to get out
of this reverse Origin Trial. Once this is approved and
developers have requested their token, we will close this
trial so that no further origins adopt the deprecated behavior.
*Reason this experiment is being extended*
We still have one of the historic users of ungated
SharedArrayBuffers which has not managed to transition to
cross-origin isolation (Google Earth). They are in the
process of deploying COEP and asked us for an extension of
the reverse origin trial until M146, when they believe they
will be done with COEP deployment. Once the extension is
approved, we'll close the Origin Trial to ensure no new users
can register.
When this was renewed last year
<https://groups.google.com/a/chromium.org/g/blink-dev/c/A4CR6MIVzds/m/CaY6sUSVAAAJ>,
we discussed closing new registrations and only allowing
exiting registrations to renew. Was this ever set up? (if so,
it seems to have regressed, from what I can tell).
