Nope, it is a good idea.

A plain washer does two main and a third things:
1, It distributes the load evenly.
2, The nut/bolt head acts on a flat surface allowing the force to be directed to the thread with lower frictional loses between the nut/bolt head and the surface component. (stops it coming undone)
And 3 stops damage to the nut/bolt head or the surface of the components.

A thread works like a wedge, two wedges being forced together it is this friction between the two wedges that holds the thread together and stops it coming undone.

Frictional loses between a rough(ish) surface and the nut/bolt head can amount to 50% of the torque applied - so just when you thought it was tight - it ain't

my 2 cents
