Until, of course, courts allow the extension of inside-the-border border checks ("What, you don't look like a US citizen to me... gonna have to detain you while we verify that since you don't have your passport or birth certificate to prove it--should have had one with you, eh?") or RealID compliant-DLs are tracked similarly...

Don't bet against someone at DHS (and a contractor who is ready to spend Uncle's $$ pursuing it) having that idea right at this moment.
