If a subfile is not certified, you cannot know whether to reference it
using INVERTNEXT or not.
You would have to turn clipping off, but why not certify the subfile first?
I don't think it will be a problem anyway, because most subfiles are
primitives, and we should agree on their orientation and certify them first.

No, we will start benefit from BFC as soon as the first part has been certified
(after having certified the primitives of course)
(and assuming models can be considered certified)

Yep.
