Nested in-context parts?

I have question about in-context parts where a part is inserted into another part. Has anyone tried using nested in-context parts? For example: part A is inserted into part B which then is inserted into part C. Another option is that parts A & B are each separately inserted into C

Why would I want to do this? The part is injection-molded as one part, and not an assembly (example: living-hinge). What are the potential problems modeling a part this way?
