I have flown Frontier as recently as Friday (MSN-DCA) and the boarding process is quite efficient - nothing like the horror of boarding a United flight. Well before actual boarding begins, you put your carry-on bag in the sizer and if it fits, the GA rubber stamps your BP (F9 does not have those pesky electronic BPs that don't work on the first try half the time).
The only people who are truly inconvenienced are the scofflaws who ignore the size rules or fail to pay the fee in advance.
