With a soft center you can simply make a new skim cut every time you install it, making it 'perfect' every time. That is good for work held between centers, but the internal spindle taper is also really convenient for many other types of tooling. A reasonably accurate spindle taper makes much work go faster.Another approach to true running centers in the headstock is to use a soft center that can be trued up in place and stamping a match mark on the spindle end and the center so that it goes in to the same location when it is used; this usually ensures that the center will run very close to true. I think that careful use of a morse taper reamer is the practical way to deburr the spindle taper.
