Maybe it is competitive now, it hasn't always been like that.

Just to give you a taste of the issues.
When I complain about something, usually it is based on experience and knowledge.
And if I wanted to have a desktop where JavaScript gets used everywhere I would buy a Chromebook instead.
My reading is that performance problems are caused by interactions between reference-counted GObjects and tracing GC, nothing to do with "not having a V8 class implementation".

Now what can we learn here? Well, the most important lesson is that getting properties from GObjects seems to be very expensive and a major bottleneck [...] Also generally (and as expected), recursive processes like Clutters allocation machinery round tripping between C and JS land are a bad idea and should probably avoid JS land altogether

This fix is strictly specific to GObjects wrapped by GJS
From my point of view, the whole experience end to end counts as having a V8 class implementation, and not the bare bones runtime.
ChromeOS isn't only V8 without anything else.
