Option for alternate ATmega32u4 package?

[ogaskell]

The ATmega32u4 is available from most sites in a QFN44 package, which is a few mm smaller than the QFP44 package the guide recommends. This smaller package allows the MCU to be placed between switches, so a keyboard can be designed with edges flush to the switches, while still being hand-solderable.

It's not that difficult to change the footprint to this alternative, and greatly improves the finished keyboard imo. This could be a useful addition.
