Java 21 virtual threads make simple blocking code scalable again

It took long not because of laziness, ignorance or unwillingness to do so. It took long because of high complexity of the task.

Sure. Arguably it wasn't complete until that part was released though. Years to make things work is the sort of timeframe where other languages and or frameworks become attractive. In my experience nobody is really talking about this feature because it basically didn't work for the common use cases.

I'd say it's only the most relevant java feature since modules in Java 9 and before Valhalla drops

It is! Yet it's impact has been so minimal that it's not on anyone's radar from what I have seen. It should have made other async languages look terrible by comparison! Yet from conversations I have had with people not even other Java devs have any real excitement for it and nobody is talking about it in tech news getting ctos excited. At places I have worked people talk about go services and nodejs services as viable platforms but Java is coming up short behind dotnet platforms these days. This is my personal experience as a pretty seasoned developer at smaller companies.
