Does this bug take the place of the "Matic's Performance Tracker" bug? (I can't find that one right now)

Does anyone pay attention to this bug?

The V8 team made a faster HTML parser and it resulted in a 3.4% increase in Speedometer, WebKit also implemented it. Could this be applied to Firefox? From here https://v8.dev/blog/holiday-season-2023 and here is the other link https://github.com/WebKit/WebKit/pull/9926

See bug 1821615 - it may be worthwhile eventually, but at the moment the bottlenecks during innerHTML parsing are in code that would also be exercised by the fast path parser (element node creation etc).

How Chrome doubled its Speedometer scores on Android (December 4, 2024):
https://blog.chromium.org/2024/12/doubling-speedometer-scores-android.html

Especially those "build optimizations" could be likely applicable to Firefox too, and the article says "these build optimizations account for more than half of the overall Speedometer score improvements".
