Hi Mike!
With the current usage measurements we see, we hadn't considered
any enterprise policy for opt-out.
But certainly can follow the process to do so if you feel that
there may be risk of undercounting.
Deprecation of WebSQL in third-party contexts added a policy that
lasted 3 milestones after deprecation before full removal as an
example.
Although the usages were quite different from that deprecation, we
can follow the same process if this sounds reasonable.
I think this plan sounds good. LGTM1 once you have an enterprise
opt-out in place that will remain for 3 milestones. Also please make
sure to communicate this change in the enterprise notes and other
communication channels.
A couple of notes I took last Friday and forgot to post:
I dumped the list of sites from HTTPArchive (query below) and after
de-duping them, ended up with 835 sites.
I then ran a script which naively looks at response codes, and got the
following results:
2XX count: 685/835
3XX to HTTP endpoint count: 74/835
4XX count: 3/835
5XX count: 2/835
So, from this dataset, roughly 9% of those redirect to an HTTP endpoint.
That said, I think reducing risk of breakage for enterprise environments
is a useful and friendly thing to do. LGTM2 w/ that done.

That said, this seems like the kind of thing that's
likely-enough to impact enterprise that we should include a
temporary opt-out to give ourselves some wiggle room if it
turns out that we're undercounting usage. Have y'all already
put something like that together?

*Specification
*https://www.w3.org/TR/webdatabase/
*Summary
*We intend to deprecate and remove usage of WebSQL in
non-secure contexts. Deprecation is targeted for M105 and
removal is targeted for M107.
*Blink component
*Blink>Storage>WebSQL
<https://bugs.chromium.org/p/chromium/issues/list?q=component:Blink%3EStorage%3EWebSQL>
*Motivation
*The Web SQL Database standard was first proposed in April
2009 and abandoned in November 2010. Gecko never
implemented this feature and WebKit deprecated this
feature in 2019
<https://github.com/WebKit/WebKit/commit/761bce943c0696a6bb93116eb0576ed07dbfdc65>.
The W3C encouraged those needing web databases to adopt
Web Storage <https://www.w3.org/TR/webstorage/> or Indexed
Database <https://www.w3.org/TR/IndexedDB/>.
WebSQL has been deprecated and removed
<https://groups.google.com/a/chromium.org/g/blink-dev/c/TM6YDx1Hh08>
for third-party contexts in M97.
We hope to entirely deprecate and remove WebSQL at some
future point when usage is low enough.

Risks
Based on usage measurements
<https://chromestatus.com/metrics/feature/timeline/popularity/4073>
rolled out in M97, 0.005% of page loads use WebSQL in a
non-secure context. Less than 0.01% of top sites have
adopted this feature.
Out of the 20 top sites listed for the month of April
2022, 11 of the sites use a feature detection library
Modernizr 1.5 <https://modernizr.com/news/modernizr-15>,
on a version released in 2010. This would create a test
database to check feature availability. I was unable to
reproduce the creation of other WebSQL databases outside
of the one created by Modernizr on these sites. 4 sites
that seem to use an outdated private mode detection script
<https://stackoverflow.com/q/48169810> which was intended
for older versions of iOS. All the scripts I have found
checked if window.openDatabase existed before usage,
likely due to the lack of support in Gecko and WebKit.
Interoperability and Compatibility
Gecko: Never implemented
WebKit: Deprecation shipped in iOS 13 and Safari 13
<https://trac.webkit.org/changeset/277564/webkit>
Web developers: No signals
