I think this becomes an issue with a hat when you try to reblock it. Pull it down onto the block can some times reveal that weaken that was done with a machine and rip the felt on the brim break where it meets the crown. Not always, but it can weaken it to this degree.
Any damage to felt from a machine stitched sweat would to me indicate one or two issues in the setup. The first and maybe most important is the stitch length. We want long stitches and not something that you would find on say the brim binding. The other would be thread tension, if the tension is too tight then it could cut into the felt. So I can see it happening but to @humanshoes point, the operator must take great care to setup the machine just right. I have done this operation both ways by hand and on the ASM clone of the Singer machine for sewing in the sweats. Reblocking would only expose an issue if proper setup wasn't performed.
