Would a simple solution just be to move the conditional points right in
close to the original points at parse time? If the length of the
conditional vectors is unimportant then you’d be decreasing the number of
conditional points that lie outside the viewing frustum. With a distance
of, say, 1/10th LDU from the line you’d rarely encounter any problems.

So I think something along these lines (or a better works-mostly solution)
would be better.

I think you’re right. I’ll look into that. It seems like the most
straightforward, and since it’s just a pre-processing step, it shouldn’t
affect the performance for anything other than model loading.

OK, I applied this fix (pulling the control points to be 1 LDU from the first
point of the conditional line), and it seems to work. It makes the “Show
control points” option under conditional lines less useful, but that’s a price
I’m willing to pay. Of course, this doesn’t completely solve the problem, but I
think that it helps enough that I’m going to live with the remaining known
problem.
