The default value is 0x56 or 0b01010110 which is bits 1, 2, 4 and 6. This is equal to:
- OD = 0 = Output Enabled
- IE = 1 = Input Enabled
- DRIVE = 0b01 = 4mA
- PUE = 0 = Pull-Up Disabled
- PDE = 1 = Pull-Down Enabled
- SCHMITT = 1 = Schmitt Input Enabled
- SLEWFAST = 0 = Slow GPIO Mode
I think this means the two lines I highlighted above are at least /harmless/, as they reset the pin to defaults, and then change one specific bit to a value that it already has in the default.

I mentioned this in matrix but didn't remember to make an issue for it.
There was another write/modify mixup caught in a review comment on the PWM rework PR, but it's good to have a reminder that it's not done yet.
