When I bought my R65, it had no E-clips. At first I thought "no big deal." Then I noticed that the seat tends to slide forward against the rear of the tank. My bike has some narrow horizontal bare spots on the rear of the tank where the forward edge of the seat had worn away the paint over the years. So I decided that it would be prudent to combine authenticity with longevity and spend 50 cents US and about 1/2 day of cursing in my garage to put the clips where they should be, in order to preserve my tank.
