LGTM3 assuming a quick check of 10 sites on the list doesn't show any
significant breakage

Yeah 0.0002% is in the grey zone of being low enough to not be a
problem. My hunch, given the lack of support in Firefox, is that
they're going to somehow not actually result in any visual change
or maybe result in some minor cosmetic issues. In which case I
think aligning with Firefox would be good and we should ship
this. Anders, can you spot check say 10 origins from the
HTTPArchive list and let us know what you find in terms of
breakage? If all 10 are unimpacted or have only very minor visual
impact, then that drops this down to the "usually insignificant"
level of potential breakage.


Yep, the fact that Gecko never felt a compat need to implement is
promising. +1 to doing a random sample to get a sense of impact
severity.



Note that I checked WebView-specific UseCounters for this and
they're 1/10th of the Android ones, so the risk for WebView is
already very low.

Could you point to a commit or a bug? I've only been able to find

That said, I'm unaware of content that relies on these two
properties (cf.

Could you point to a commit or a bug? I've only been able to find 
https://bugs.webkit.org/show_bug.cgi?id=240271, which suggests that the 
prefixed variants do exist (and devtools will autocomplete them in the 
latest Safari Tech Preview 156).


That said, I'm unaware of content that relies on these two properties 
(cf. https://compat.spec.whatwg.org/#propdef--webkit-perspective-origin).


thanks,
Mike

   - Gecko does not support it. No support for those properties with the
   -moz prefix either.
   - WebKit does not support it (anymore).

[blink-dev] Intent to Remove: -webkit-perspective-origin-[x,y]

[Anders Hartvoll Ruud]

Contact emails


*andr...@chromium.org *Explainer


*None*Specification


*N/A*Summary




*Removes the non-standard -webkit-perspective-origin-[x,y] CSS properties.
Note however that the -webkit-perspective-origin property (an alias of
perspective-origin) is not affected.The regular (parsing-based)
use-counters are at about 0.5% of page
loads.https://chromestatus.com/metrics/css/timeline/popularity/310
https://chromestatus.com/metrics/css/timeline/popularity/311
However, a
typical pattern is to specify the same values both for a prefixed version
of the property and an unprefixed version in order to cover as many UAs as
possible. For those cases removing support for the prefixed properties
likely has no effect. In order to measure this, a use-counter was added to
find whether or not the prefixed properties actually make a difference to
the relevant computed values. This use-counter sits at ~0.0002%
 of page
loads.*Blink component


*Blink>CSS
*
Motivation



*The -webkit-perspective-origin-[x,y] properties overlap in a non-trivial
way with another standard property (perspective-origin). This situation is
not supposed to exist, and therefore the interaction
-webkit-perspective-origin-[x,y] and perspective-origin is not defined by
any spec.*Initial public proposal


*N/A*TAG review


*N/A*TAG review status


*Not applicable*Risks

*Does this intent deprecate or change behavior of existing APIs, such that
it has potentially high risk for Android WebView-based applications?*
