I can not understand this: what kind of features are so different that
you can not include them into a single firmware image? Please enable all
users with all possible features instead of tying them to a product
segment. If I'm missing something, please provide additional
information.

Why do you need even more nesting for IoT products? "qca/iot/ROME/QCA6390"
also looks strange, but perfectly possible with your patch

Without the IoT platform you can just include a static string.
