Stones are used because one can etch a pattern into them, no? If you're not doing structure, why stones?
I will not profess knowledge, only experience base on "related process".
Stones offer the "possibility" to effectively remove base material while still holding up against occasional contact with the steel edges.
The "real ski tuning machines" would prefer that the two materials only contact grind wheels designed for the task. That is, the base grind stone is NOT the same stone as the base edge bevel stone. The stones themselves for each application differ in "friability" optimized for the task. A "base stone" that sees too much edge metal, soon looses it's shape, and becomes grooved.
Belts behave in much the same way, with the metal ski edges taking the "sharpness" off the belts more quickly than is prudent for economy.
Structure? Any base processing will result in some form of surface structure. Whether it is the pattern popularized and promoted by commercial ski tuning equipment manufacturers is an entirely different topic. As mentioned in a previous post. Turn all results into a feature!
And a few passes with a sharp scraper will have any resulting "structure" reduced to insignificant in a jiffy! ;-)
