TSA/DHS badly wants to keep dossiers of our domestic travel history for use in data-mining our associates, homes, destinations, etc. (i.e., "secure flight" derivatives) so that they can have even more false positives that harass even more innocent US citizens. There's no reason to make it that easy for them to do so.
This is the exact reason why I will not use the CO PDA-based BP option (
being tested now in IAH), since it requires allowing that information to be scanned by TSA at the CP.
