I would suggest that filled mode is applied whenever there is a partial
hatch opening. Obviously the smarter "correct" mode will result form the
rounding radius, e.g. the 2*radius defines the smallest opening
dimension. Small sharp corners are very bad for processing as they etch
and wash with difficulty. So there will be more ionic contaminants on
the board under the solder mask and possible corrosion and isolation
problems.
