The Network API spec[1] doesn't allow identifying the current carrier, nor
does it provide information on whether the device is roaming or not. It
also doesn't provide any info whether or not the current network access is
metered, limited in anyway, etc., nor does it allow picking a different
network.

I'm not suggesting the use cases listed so far are not possibly valid ones
(though I would argue alongside the lines of Josh that they might be
better, less network-dependent ways of fulfilling the underlying use
cases), but the Network API in itself doesn't enable any of them nor are
there any other existing spec that could help with this.
