I do think it’s binary. The project either shows potential to meet your goal or it doesn’t.

I think it’s rare that fails to show potential because of the underlying technology that’s chosen.

Sure, Vercel is relatively expensive. But I just don’t see how you’d throw in the towel because the costs are too high without first evaluating how to lower them.

If you’re saying that the evaluation is likely to show that you’re stuck - I have never seen that be the case personally.
