Upnp and chromecast have quite some stuff in common. I think its all politics and messed up standardization. Add some recoding services like bubbleupnp server, browser support and dlna can still serve as a nice alternative with tons of hw. But people like their locked ecosystems and are not willing to invest in interop.
Upnp was build for home automation so i guess it was too ambitious considering the company political minefield. Its successor dpws lives in an equally strange niche now: printer autoconfiguration. The open source community never cared much to provide robust free implementations. (I wrote upnp and dpws gateways for smartdevices more than 10 years ago and the situation hasnt changed since)
