I guess it's no different to when different browsers support different
media encoding formats. But to me it makes no sense if every browser
supports a different manifest format. That just increased the
complexity of the Web manifold - seeing as for the "Web" to work, you
need browsers and servers and proxies. In short, I do see a need for
an adaptive streaming manifest format to be standardized across
