Agreed, @gmandyam. This was really a note for me so this doesn't get 
lost. To answer your question, it seems that when the fusion happens 
at the HW or underlying platform -level, then the fused(?) sensors are
 exposed as if they were a unique data-source to the Web platform. 
Afaik, this is how Geolocation already works (fusing GPS, WiFi, and 
network data, in a way that's totally opaque to the consumer of the 
API). This is good and should continue like this.

What might be worth enabling however, would be to give (Web) 
developers the power to create their own sensors from the fusion of 
multiple sensors and exposing them as a single data source. Imagine, 
for example, combining various sensors to create a high-level 
`AirQualitySensor` based on a given [air quality index][1] which would
 have the same interface as if it was built at the HW or underlying 
platform level.
