Oh wow, I had no idea that was a feature. That significantly hampers extending the tools in the future. Has there ever been a discussion to consider breaking that functionality? (I understand it could be a huge impact & not worth it, but just curious to read the discussion if it exists.)

I can't find any discussion. But I know that some alternative implementations disable this feature. The cause of this behaviour is actually the glibc `getopt_long` function, which does this automatically, so it can't be changed until it's changed in glibc, which has been rejected at least once that I can find: https://sourceware.org/bugzilla/show_bug.cgi?id=6863
