I'm pretty receptive to the privacy concerns as they are similar to the existing work on protecting local IP addresses. 

However I disagree that this information is not useful; the single bit of information to identify wifi versus mobile data, even as a noisy signal, has proven to be of significant use in debugging production services. (i.e., a surge of issues predominantly on mobile data can indicate a problem in a specific carrier's network).

My recommendation would be to treat this as privileged and only give it out when trust has been established, rather than removing altogether.
