Specification

Summary
Removes support for the non-standard "zoom" CSS property. This CSS
property causes computed lengths for an element to be multiplied by
the specified zoom factor.

Risks
Interoperability and Compatibility
This feature is only available in Webkit and Blink-based browsers, and
has been present in Chrome since the beginning. Usage is a little
above 0.5% of page loads:
https://chromestatus.com/metrics/feature/timeline/popularity/3578
However, research shows that sites in HTTPArchive triggering the
feature mostly don't even seem to use it, and those that do appear to
always use it in a way that works fine without zoom applied - worst
case, just a very minor change to the size of a tiny number of UI
elements, but the UX is basically the same. See:
https://docs.google.com/document/d/1cmbXpjAcXAht2ufi7bNKy-rbVNveqaf0UzeYg_DIMNA/edit#
It would also be good to go through all duplicates and "See Also" bugs
linked at https://bugzilla.mozilla.org/show_bug.cgi?id=390936 and see
how we fare with a build that has zoom disabled.
/Gecko/: Shipped/Shipping (Firefox never supported the feature.)
/WebKit/: No signal
(https://github.com/WebKit/standards-positions/issues/170)
/Web developers/: Some web developers like the feature, in particular
for the use case of zooming in content in a legible way with
responsive design. See comments regarding that in this issue;
https://github.com/w3c/csswg-drafts/issues/5623
/Other signals/: The CSSWG has decided to not specify this feature:

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?
Maybe. WebView-based apps might use this feature.
Debuggability
Sites should be able to see that zoom no longer applies to elements in
devtools, though there is no warning planned.
Will this feature be supported on all six Blink platforms
(Windows, Mac, Linux, Chrome OS, Android, and Android WebView)?
Yes
Is this feature fully tested by web-platform-tests
<https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md>?
No
Flag name
CSSZoom
Requires code in //chrome?

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).
None
