I'd always thought that was so the center could take stamped info,
before the final dimensioning. If you're grinding the exterior,
there's no big savings in time or trouble; the whole length is
done in one pass.

And leaves a goodly section that can be damaged, ruining the fit of
the whole taper. Shrug
