On use of "POCO secondary cable"—there is another problem. With most {NEC/UL} building wire, the aluminum conductor is "AA8000-series" which is alloyed with a small amount of iron, and is far more resistant to smack-you-in-the-face installation springback and coldflow problems. AA8000 conductor has been readily available for about 25 years.
Instead, for "secondary" cable, older '1350-alloy' material is often used, but is more typically installed with nonreversible hydraulic-compressed terminals and splices. So for building wire, "good enough for PoCo" is likely not the case for Code applications.
