Given that having the source code to a system is a necessary part of modern security practice, it would actually be a very good precedent.

This assumption that it's alright for communications infrastructure to rely on trusting black boxes as long as those black boxes were designed by "allied" companies is madness. It doesn't particularly matter whether the gear is made by Qualcomm, Cisco, or Huawei - it's all suspect.

The ultimate path forward is for mobile nodes to stop trusting the network, entirely. But that's a long row to hoe with regards to access authorization without leaking identifiers.
