Yes, you will need to for JavaFX 8 since there is only one vertex
format. We have plan to add more in future releases.

Flat shading isn't in our plan but we may consider it if you have a
good 3D use case. Can you elaborate your question on smoothing group number?

No, we didn't specify much about its restriction. It may be good to keep
this within a small positive range. We may have to tighten later as we
work out some of the details.
