The idea behind shaving tyres is not that a reduced tread increases traction
because a full tread flexes though that it is a factor. It is rather that
the tread edges by flexing overheat and traction and tyre life (even for
racing) is reduced. By shaving the tread depth down the tyre works within
its effective range.
I have not heard that racing slicks get shaved but rather that they get
buffed to remove the shiney surface finish left after manufacture.
A lot of folk used the terms buffing and shaving meaning the same thing when
they are 2 different things - at least in the Uk.

that full tread flexes during cornering and cause a loss of traction. Since
the tire is mounted on a machine to spin it and the cutting edge is
stationary, the result is a perfectly rounded tire on that particular rim.
Shaving a racing slick is strictly for rounding it unless they are shaving a
used tire. Used tires, however, are rarely shaved unless they are just
barely used and the rim is changed for whatever reason. I'm not familar with
the term "buffing" when applied to tires.
