This is a really weird grey area, though that I haven't seen a similar case of elsewhere. You are creating confusion by using terms that 90%+ of the electric vehicle charging community has never even heard of and doesn't know exist and conflict with the commonly known terminology. Yes, I know that the references you are citing are the official documents, and that is officially how it is in the published specification sheets, and I have no idea how it morphed into the form it is now, but we are where we are, and it is commonly known what "Level 1", "Level 2", and "Level 3" charging are. So it is kind of confusing people to tell them something that doesn't match all of the common usage, despite it being what is in the technical documents.Using non-existent levels is just creating confusion.
I do sympathize. It's like the prophet crying out in the wilderness. He's correct, but the people are ignoring him. I don't know if there is any good solution.
