Because VFP has inhertiance it isn't such a big deal AFAIK, although it used mimiced. See article#224 Designing Your Own Framework by Jim Booth. He uses Abstract classes to define interfaces for the framework.

AFAIK COM is where it becomes important. I'm just learning how all that works so I can't really discuss it much. Wrox Press has a really good book on COM with VB that discusses it fully.
