Saw that.  That one is on the rim manufacturers.  To be sending out rims with edges that can cut tires, especially on race bikes where tire casings are minimal, bikes are regularly ridden out of saddle and are cornered hard?  Is this a plan to reduce their market?

Leonard Zinn makes an interesting point,  Aluminum rims are drwn through a die that is milled.  Milling cutters cannot do sharp edges parallel to the shank because they spin.  So no aluminum rim will ever have a sharp edge.  But CF rims are molded using two piece molds.  The rim beads are the logical place for the pieces to mate.  This means flashing - thin, brittle and potentially both very sharp and jagged.  Perfect for sawing tire casings.

Lesson?  Check those beads and be prepared to sand.
