Right, and often the tested depth isnt maximum. So you slowly acclimate to worse and worse code practices if the effort needed to undo it is the same as doing.

sure, but undo isn't the only path to a newer better version of the code

it's easy to see how the product (claude code) could be abstracted to spec form and then a future version built from that without inheriting previous iterations tech debt

That’s the rub, yes - as long as your failures are nice and gradual and proportional to the changes you’re making, everything’s fine.
