Thanks Di - this is a useful clarification.
You can request up to 6 milestones for a Deprecation Trial, and only
need a single LGTM. Renewals are possible, with sufficient justification.
That said, if you do think that 9 milestones is sufficient for your
needs - that is also possible, but will require 3 LGTMs. If that is the
route you would like to propose, can your let us know why you think 9
milestones is sufficient, and wouldn't require a renewal? What outreach
or comms plans do you have in place to ensure that the previously broken
sites will be ready for this change in ~9 months?
Either way, please let us know how many (and which) milestonesyou are
requesting for the deprecation trial.
thanks!
Mike

Sorry for missing information! I haven’t created a request for a
Deprecation Trial before, which is what I intended this to be, and I
missed some parts of the process. The chromestatus is located here,
which is for the overall KeyboardFocusableScrollers feature:
https://chromestatus.com/feature/5231964663578624
<https://chromestatus.com/feature/5231964663578624>. The origin trial
section details why we are requesting a Deprecation trial for this
feature, which I’ve copied below. I believe this answers the questions
I’ve received here, but please let me know if anything else is missing!
Summary
The feature KeyboardFocusableScrollers changes the focusability of a
scroll container. This feature includes the following changes:
*
Scrollers are click-focusable and programmatically-focusable by
default.
*
Scrollers without focusable children are keyboard-focusable by
default.
This is an important improvement to help make scrollers and contents
within scrollers more accessible to all users.
We attempted to ship the above changes, and found that a limited
number of sites had broken expectations around some of their
components. As a result, we had to unship the feature to avoid this
breakage. However, given the benefits mentioned above, we’d like to
ship this feature again.
To allow more time for the affected sites to migrate their components,
we are requesting a Deprecation Trial. This trial (called
“KeyboardFocusableScrollersOptOut”), when enabled, will disablethe
KeyboardFocusableScrollers feature. To give adequate time, we’d like
to let this deprecation trial run for 9 months. It might be ok to
limit this to 6-months, but would like the option to extend the
depreciation period if needed.

There's a lot of information missing from this Intent (see

<https://groups.google.com/a/chromium.org/g/blink-dev/c/LwgSKPBivuM/m/0dRsXWhBAgAJ>
as what is typical) - could you reply with the missing info?
(Did you use ChromeStatus to generate the email?)
Also note that origin trials can only run for 6 milestones
initially (see
https://www.chromium.org/blink/launching-features/#origin-trials
<https://www.chromium.org/blink/launching-features/#origin-trials>)
- or are you requesting a deprecation trial?
FWIW, according to
https://www.chromium.org/blink/launching-features/#deprecation-trial
<https://www.chromium.org/blink/launching-features/#deprecation-trial>,
deprecation trials also only run for up to 6 milestones before
extensions

*Experiment Goals*The feature KeyboardFocusableScrollers
changes the focusability of a a scroll container. This is an
important improvement to help make scrollers and contents
within scrollers more accessible to all users. The goal of
this experiment is to collect feedback on this change from
users who might depend on the previous behavior (when a
scroller is not focusable by default) and help them adapt to
the new behavior which will ship in M126. Sites can use this
Origin Trial to opt out of the KeyboardFocusableScrollers
feature.
*Experiment Risks*This experiment is to allow users to
opt-out of the feature KeyboardFocusableScrollers. There is
no risk to loss access to any important API or other
functionality.
*Ongoing Constraints*None
