As someone who designs IoT devices like these for a living, the device manufacturers here are in many cases the smallest companies in the supply chain and have very little ability to influence things upstream of them, especially for specialty products or companies entering a new market. It's often a major win to get a chipmaker to pick up the phone and sell us their product, much less receive any support at all.

I wish I could put a label like this on all of my products and I've been wishing for this for over twenty years, but the reality on the ground is that our support ends when the support for the individual parts in our product ends. We've looked at our supply chain periodically to see if we can replace parts with better documented/supported comparable parts, but frequently there just really aren't any better options.

This is a great idea in concept, but I fear that the flaw in the FCC's proposed rulemaking is that only indirectly addresses the root cause (the software, documentation, and support/updates provided by chipmakers for their parts). Furthermore, by focusing on device manufacturers who are the weaker partners in the chain, the regulation is likely to punish smaller, more innovative manufacturers.
