Should (solder) jumper footpirnts define a mask cutout between their pads
See https://forum.kicad.info/t/should-jumper-pads-have-solder-mask-between-them/20998
The argument for adding an additional mask only pad is that it would be easier to cut the trace or to solder it shut (depending on type). I do not know if there would be downsides.
