USB DFU on 28pin STM32F042G

Does the 28pin STM32F042 still support DFU over USB even though the USB pins PA12 and PA11 have to be remapped to PA9 and PA10? I want to use DFU to program my part at factory so it will be blank.

And how would the bootloader know what you intend to do in your firmware? (i.e. the answer is yes).

I'm not sure it will fit.

I tried CDC on the F042, it does not fit.
