Given that Kelsey gave you a private positive signal and the spec is
merged, that works for me.
LGTM1 to ship.

The PR has been merged into the WebGL spec, viewable at
https://registry.khronos.org/webgl/specs/latest/1.0/ . Are OWNERS here
comfortable taking that as a positive signal from Mozilla/Apple?

Specification
https://github.com/KhronosGroup/WebGL/pull/3222
Summary
WebGL allows rendering into textures and renderbuffers of
many different pixel formats (e.g, 8-bit, floating-point,
sRGB-encoded, etc). The drawing buffer of WebGL (the
buffer that is passed to the compositor) is 8-bit by
default. This feature allows WebGL to configure the pixel
format of this drawing buffer. This feature enables WebGL
developers to: * avoiding an an extra copy convert their
rendering to the default drawing buffer pixel format *
draw content that has a more than 8 bits of precision The
latter feature unlocks several additional applications *
very wide color gamut content without loss of precision *
medical applications which require >8 bits of precision *
high dynamic range applications (when available)

/Gecko/: Positive Feature authored by Mozilla.
If they didn't tell you specifically that it's not necessary,
please file one, thanks.
FYI Mozilla's rep (and author of the drawingBufferStorage spec)
gave a thumbs-up on Khronos' private WebGL working group mailing
list. I'll work to get
https://github.com/KhronosGroup/WebGL/pull/3222 landed; I think
that should suffice as signal from Mozilla as well as other vendors.
-Ken
/WebKit/: No signal
(https://github.com/WebKit/standards-positions/issues/278)
/Web developers/: Positive Positive feedback from several
high profile web developers - 3D engines that use
physically based rendering - image editing formats
(especially for HDR) - medical imaging applications (which
require >8 bit precision)
/Other signals/: This feature's specification was authored
by Mozilla.
Ergonomics
None.
Activation
No.
Security
None.
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
Debuggability
No additional debugging support should be needed.
Will this feature be supported on all six Blink
platforms (Windows, Mac, Linux, Chrome OS,
Android, and Android WebView)?
Yes
The underlying technology (floating point textures) has
almost universal support.
Is this feature fully tested by web-platform-tests
<https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md>?
No
This feature is fully tested using WebGL conformance
tests, which has been checked in.
Flag name on chrome://flags
Finch feature name
None
Requires code in //chrome?
False
Availability expectation
Feature is available on Web Platform in less than a year
following launch in Chrome.
Adoption expectation
Several specific partners have been using this feature
being chrome://flags' "experimental web platform
features", and intend to adopt this as soon as it is
supported.
Estimated milestones
Shipping on desktop 122
Shipping on Android 122
Shipping on WebView 122
Anticipated spec changes
Open questions about a feature may be a source of future
web compat or interop issues. Please list open issues
(e.g. links to known github issues in the project for the
feature specification) whose resolution may introduce web
compat/interop risk (e.g., changing to naming or structure
of the API in a non-backward-compatible way).
