That brings me to the next question that you raised. Why are some "holes" tear drop shaped?

The teardrop shape is the profile of a cylinder with 45° angles above. Our commercial FDM machine can make a 45° overhang without support material, so - if you want a horizontal hole to put a cylinder through - the teardrop profile gets made without support. This is both faster and neater. And for the vast majority of cases it doesn't matter that it is not completely round.
The teardrop is also an important example of the fact that, with this technology, complexity of shape costs nothing.
