Yes, and I did recognize I was talking about a different vulnerability by saying that the perfect is the enemy of the good. But if we're talking about protocol vulnerabilities, why skip over the deep flaw of having fixed identifiers in the first place?
Heck, simply removing the IMEI so that users don't have to buy a new burner phone (/mifi) along with every burner SIM would be a vast improvement!
Really I'm just pointing out the larger context, as it's important to keep in mind. Shoring this up will make the keystone cops have to go get a warrant, but won't help versus the NSA, parallel construction, or GoogleNexis. It probably won't even make private investigators have to eat lunch in their cars again.
