Hi Boris,

Did the CSS WG agree to ship the 3 transform functions? CSS Transforms level 2 
is a working draft at the moment. It does describe 3D transforms and 
corresponding CSS properties as well but they shipped prefixed at a time where 
there weren't feature flags. For the 3 properties you propose shipping the 
situation is different.

Greetings,
Dirk

Subject: Intent to Ship: [css-transforms-2] Individual Transform Properties 
(i.e. translate, rotate, scale)

Hi, All

As of Firefox 72, I intend to turn the preference of individual transform
properties, layout.css.individual-transform.enabled
<https://searchfox.org/mozilla-central/rev/cac340f10816707e91c46db6d285f80259420f07/modules/libpref/init/StaticPrefList.yaml#4932>,
on by default on all platforms. Blink has implemented it behind the
experiment flag but Webkit doesn't support it yet. There are three
properties defined in individual transform properties: translate, rotate,
scale. Their rendering results should be equal to translate(), rotate(),
and scale() functions on transform property.

*Bug to turn on by default*:
https://bugzilla.mozilla.org/show_bug.cgi?id=1424900

*Spec*: https://drafts.csswg.org/css-transforms-2/#individual-transforms

*DevTools*: We don't support DevTools for individual transforms now.

*WPT*:
