There may be one advantage (albeit slight) to wiring a "dedicated
circuit" for a stationary tool, particularly in shops in "garages" ... a
"dedicated circuit" is exempt from being GFCI protected in many locales.

At one time in the early days of GFCI, it was worth doing so as to not
have to deal with nuisance trips, which are no longer the problem they
once were.

You may be spot on this. I only do commercial industrial so I'm not
right up on residential but I believe all garage circuits require gfi.
There are exceptions for appliances and dedicated circuits. May be a
drawback garage shops, but I think most repair shops are now required
to have gfi circuits.
