In guessing being able to advertise lighter weight with little to no extra cost for the manufacturer. Aluminum freehub bodies should be shunned on anything with shallow splines but manufacturers want compatibility and light weight. The Sram red cassettes work pretty well on aluminum shallow-splined freehubs due to their single "carrier" on the 7 largest cogs.
