It is, but it's not very important.
The trade off is not worth it.
If you see it in time, you can avoid glass on a trike. You can always stop and go around it. I go around glass on a trike every week in the summer. I don't even think about it. You can miss many things by having it go between two of the wheels when you get used to it.
The extra weight and the wheel is not worth it. It's another thing to make it more work all the time. A trike is slower and heavier that a bike, a quad is slower and heavier that a trike.
The reason bicycles are so efficient is the fact that they have only two wheels. It's a big deal.
