Using LLMs to bootstrap development in unfamiliar frameworks is a valuable approach when balanced with pragmatic engineering principles. While framework idioms are important, they're secondary to delivering working, maintainable software that solves real problems.

The focus on "terrible structure" misses the point - what matters is whether the system meets its requirements efficiently and can be maintained effectively. Have you measured any actual negative impacts on system performance, maintainability, or customer value? My experience suggests that starting with working code and iteratively improving it as patterns emerge often leads to better outcomes than delaying development for complete framework mastery.

The interview analogy is particularly misleading - success in a software engineering role isn't measured by framework knowledge, but by the ability to deliver value to customers effectively. Learning framework idioms can happen in parallel with productive development, especially when using LLMs to accelerate the initial learning curve.
