One can easily specify a field with the endian type or with the right endianness, so using the endian types doesn't preclude mistakes. However, I concede that writing procedural code to swap each field, including newly added fields, is more brittle.

Presuming that the function approach is more efficient, I can imagine writing code with the endian types and, when performance becomes an issue, switching to normal types plus swapping function calls.

Having the choice is valuable.
