nit: It's not wrong to assert that the microcontroller software will prevent the output pin from ever floating. And the gate's voltage will be constrained between Vdd and Vss due to the output pin's likely body diodes. Is it worth it to save a penny part, especially in a hobby/prototype design? No.
Also if you throw away all your BJTs, what do you use to drive the gate capacitance of your fancy FETs?
