Those who remember the hell that was VBScript in the browser, know that having support for more than one front-end language is not such a good thing. Web developers have benefited from having javascript as the only language supported by browsers. Language fanboys might bash javascript, but there are many examples of the great things that can be achieved with javascript that make them look really quite silly, and every language has its pitfalls. Javascript is not a bad language, but it is misunderstood and people who misunderstand it are the most vocal detractors. Opening up the browser to many languages causes the tower of babel all over again. Now front-end devs won't just be required to be a "javascript ninja", they will now have to master many other languages in addition to all of the DOM wackiness that comes with supporting multiple browsers. It's all just too much.
