Too many default tags make it harder for other mappers to spot the important tags too. I have had issues with one mapper, who seemed to have a lot of time on his hands, armchairing pointless tags such as oneway=no, bicycle=yes, motor_vehicle=yes to roads. The problem was he was hiding incorrect tags in these list such as lanes=2 on single track roads and cycleway=both on roads with no cycleways.
