I never tightened cassettes to 40Nm, either. Usually stopped around 30Nm, never had one come off or get loose on it's own, but much easier to remove when I needed to.

I've seen people recommend ~50Nm for alloy body HG cassettes to limit the 'bite marks' steel cogs can make. Using steel HG bodies I haven't tried it, but a lot of WW users said it helped them and did not cause other issues.
