USPS Insurance?

[mc12345678]

Is there any way to petition USPS or ask them to make insurance a fully functional feature?

Ah ha, so now the perspective is understood. If such a petition were sent to the USPS, a conversation internal to the company similar to the following might occur:
Rep1:"But we offer all of these options as available to be used by programmers, why is someone asking us to do what we have already provided?"
Rep2:"You know I was looking at a couple of different groups that have or have not implemented this and well this one site, they seem to work off of each other and build these programs to do a lot. Seems that they have an entire ecommerce store that is built entirely from code that has been contributed by other authors."
Rep1:"Yeah, so what you're saying is that everything that is used to operate that ecommerce store is written by contributors?"
Rep2:"It sure is. As we have added capabilities, someone has to figure out a way to tap into that functionality and to do so with consideration of the largest audience. Sure the USPS module well predominantly serves just the US, but some of the same can be said about other postal methods. So what's the issue?"
Rep1:"It seems that no one has devoted all of the necessary resources to add the functionality so that a customer can choose certain items that we offer, but instead the functionality has been incorporated so that the store owner can choose to factor it in or not essentially for all items."

That's just my thought of a potential conversation related to this. The "official usps plugin" is considered official by the authors and significant contributors to ZC, not the USPS. The USPS does not control the code that is provided here, but instead provides resources to be able to access their information and the code that is written to do that is by public individuals willing and able to provide such a product.
