It's perfectly fine to require a parameter to be non-NULL, and just
crash if it isn't. You'll get a nice backtrace, or at least an
exception, which helps debugging as well.

Similar as above. In general if Windows doesn't check something, we
don't either. However, it's worth noting that if we'd be writing to
that index we sometimes do check those, because there's the potential
for memory corruption in those cases.
