Re: [csswg-drafts] [css-2025][mediaqueries-5] Add features from Media Queries 5 to Safe to Release Exceptions (#12754)

The CSS Working Group just discussed `[css-2025][mediaqueries-5] Add features from Media Queries 5 to Safe to Release Exceptions`, and agreed to the following:

* `RESOLVED: add the subset identified by SebastianZ to the safe-to-release set`

<details><summary>The full IRC log of that discussion</summary>
&lt;florian> SebastianZ: I triaged which features have good coverage and interop on the basis of having edited the wpt inline into the spec<br>
&lt;florian> SebastianZ: I'd like to go through the list maybe<br>
&lt;florian> q+<br>
&lt;astearns> ack florian<br>
&lt;astearns> florian: the ones here seem fine<br>
&lt;astearns> florian: one may show we have insufficient tests<br>
&lt;astearns> florian: scripting has 100% pass, but it does not test much at all<br>
&lt;astearns> florian: this might be true for the other features<br>
&lt;florian> florian: nevertheless, I support this set<br>
&lt;florian> ChrisL: I think it's fine, but I don't have strong confidence<br>
&lt;florian> astearns: me too<br>
&lt;florian> astearns: I think these are quite widely used anyway<br>
&lt;florian> RESOLVED: add the subset identified by SebastianZ to the safe-to-release set<br>
&lt;dbaron> FWIW Chrome has a real implementation of the scripting feature: https://source.chromium.org/chromium/chromium/src/+/main:third_party/blink/renderer/core/css/media_values.cc;l=575-584;drc=48d6f7175422b2c969c14258f9f8d5b196c28d18 though it only ever uses 2 of the 3 values<br>
&lt;florian> astearns: I was a little concerned about the pass rate, but most do seem to have 2 implementations<br>
