First time I saw washers under the baseplate was in a SOTD photo. I thought ... WOW ! ... that's so 'anal' !
Then a friend loaned me a Ti WR2 for a whole week and stipulated that I always use a washer.
So I've been using one on any razor that it fits ever since.
I went to Ace Hdwr and bought a gang of them.
The two razors that don't fit off the top of my head are Charcoal Goods SS, and Blackbird.
The end of the handle fits into a recess in the baseplate precluding the use of a washer.
They are not 'necessary', but I like protecting that bit of finish. YMMV.
