Once we implement the TLS 1.3 cipher negotiation, we'll need to make sure both DevTools, the Android connection tab, and other consumers of the cipher suite strings API all handle this properly.
The current plan for DevTools is to show "Key Exchange" and "Key Exchange Group" as separate fields and just one or the other may be missing.
The Android tab we'll have to figure something out. That's done as one string, so the optional fields may be tricky.
