Those implementations were created to be utilised within FirefoxOS where applications are granted permissions by user when installing them. And access to several API would be strictly regulated by OS it self.

In Web context this approach wouldn't work and would lead to security issues. Just like there was need or WebSockets (TCP), there is need for similar API for UDP but it cannot be pure access for creating UDP connections as this leads to many security concerns.

I am a fan of the "just stick a security popup and let people choose" option but I understand that is not the same as having proper security.
