Definitive answer---------Any light fitted should be in working order, cutting wires and removing bulbs to make the light inoperative while the actual fitting is still there is not acceptable
Think about it,IT IS JUST THE SAME AS HAVING A BROKEN WIRE OR A BLOWN BULB
which would be a MOT fail.
Rear parking light is also your tail light so by removing the front bulbs you only gain fractional reduction in battery drain
Like the man says---Checking to make sure your lights are off when you leave the bike is the easy solution
