While your examples might sound like a similar situation, I'd argue they differ in significant ways. Web was and is the largest software delivery platform. From that perspective it's more akin to x86 machine code. For a long time it was the format you needed to output to partake in that ecosystem without alternatives. A more fitting comparison in my eyes is Kotlin for Java. And if there would have been a single project the community backed, I could have seen a similar situation arising. But as it stands, I don't see that happening.
