Checking this value at the source of obtention and providing and earlier
return with arguably a better return value, all at the cost of an
inexpensive pointer comparison to NULL doesn't sound like a terrible
idea.

If you were committed to the idea of removing it, which I suggest you
reconsider, I would insist that you replace it with at least a comment.
