But that repurposing/removal is exactly what's avoided if you follow through with the SEF framework he outlines.

I have to push back on the idea that token costs balloon when using TDD within the context of a strong framework such as Jason has laid out here.

If the feature is repurposed/removed/refactored....I'd argue the specification wasn't well thought out prior to burning into tokens.

We're so eager to do a lot of the wrong things quickly, when it may serve us better to do a more precise thing slowly.
