Ted it won't make any difference that you would care about with your 35, 50
and 90.
the 15 and 21 will vignette more and maybe have coloured corners but you
might not notice that for many shots.
It helps for identifying the lenses afterwards. Since you already have
hundreds of thousands of shots without that info, I doubt that you care.
It helps with flash. I KNOW you don't care!
Cheers
