I've been wrestling with something similar lately (unrelated data wrangling), and ended up having to bypass pandas completely, as having Nones in columns messed up the `dtypes` (got exceptions when trying to force them in afterwards). Not sure if this will be solvable with the current stable pandas version (apparently they introduced better nulling support in 0.24), but keeping fingers crossed these things get better support soon (guessing arrow will supercede pandas for this type of data processing).
