I do not think the connection type should be exposed to content. It's
something that could be exposed to some content behind some permission
model but not regular content that doesn't require any permission.
As I said in my initial email about the Network Information API, there
are three major reasons:
- fingerprinting: it's adding a few bits of entropy;
- privacy: you can deduce a few things based on that information: 3G or
up would usually be in big cities, other mobile connections would be in
country side or some places with bad connectivity (like metro) and the
most important is that wifi usually means you are in a place you go
often (home, work, friend's place, ...);
- bad assumptions: people will assume your connection is slow if you are
using a mobile connection that is "2g" for example.

I'm open to alternatives.
