@tJener that is correct. As @nikic pointed out in a chat, this tool looks 
unmaintained. Most of the content changes in 
[here](https://github.com/llvm/llvm-project/blame/main/clang-tools-extra/clang-change-namespace/tool/ClangChangeNamespace.cpp)
 look like as if they are 9 years old. The fact that you, @tJener and 
@AaronBallman ask these very specific questions lets me think that it is also 
not in active use. I'm going to go on PTO soon but I will put all my questions 
on my list to address when I'm back.
