i had actually thought about that a little bit. my logic is, if the pipe freezes, most likely the water will be frozen as well, so it won't be leaking in the basement. the worst case is if the outlet freezes and dams up where it gets shallow but the heat from the house and the ground keeps the water liquid around the foundation. i'm hoping that it will drain enough away and any water that falls on the surface (snow/ice/freezing rain) will not penetrate the frozen ground until the pipe thaws.
we have several other shallow drains (two buildings have shallow gutter downspout drains and we have a grey water drain on the shop building) and have not had a problem with freezing blocking the water. of course, we are zone 6/7 but we do get down to near zero every winter. i think if you are moving warm water, you won't have a significant freezing problem.
i suppose in the exteme, you could wrap your exit pipe with heat tape anywhere it rises above the frost line.
or use a pit and pump method instead of draining to daylight.
most full basements if done properly use an internal drain with sump so the external pipe is just extra insurance.
maybe someone with more "northern" experience will chime in?
