I spoke with Justin about this and he said this topic came up in the program call when they discussed collecting all areas that do not support IPv6 in 6.17.

They're still considering the best approach—whether to consolidate all unsupported features in a single location, distribute them across relevant sections, or include them in multiple places. This may require a larger discussion on how they want to handle it. But he thinks having it in too many areas of documentation might be too much and thinks for now this single location will suffice. He also said Ioanna was part of that conversation and he sent her the ticket he had created on this topic.
