Detecting connection speed in a useful way is a very difficult problem, 
not least because it's often a time varying quantity (consider a mobile 
device that might switch between wifi, 3G, 3G but with high packet loss, 
and no signal at all, all in the course of interacting with a single 
page). I think that in general trying to expose this kind of data can 
lead to worse user experiences than not exposing it (e.g. if pages 
erroneously shift into some sort of "low bandwidth" mode due to some 
temporary network congestion or whatever). Therefore I don't think this 
should be something that we expose, unless it is clear that we can do it 
in a good way that will solve actual problems.
