This check is done by every airline I can think of. What seems to be your objection to it? It seems to be standard procedure around the world to check your BP at
1) The security area (to prevent unauthorized access to the airside areas)
2) The boarding gate (so boarding staff can identify who has turned up and who has not and to prevent any randomer walking around the ramp)
3) The aircraft door to make sure the right person is on the right aircraft, going to the right place.
4) Headcount - to check the passengers boarded matches the manifest.
I don't think I have ever been on a flight where this sequence of events has not happened and I'm fine with it. Keep your photo ID and PB handy at all times and very little of your precious time will be wasted. FR boards its aircraft so quickly anyway that it should not be an issue!
