The problem is that older versions of CMake are still around and will stop working with up-to-date Flang, risking complaints from users. This includes LLVM itself which still supports CMake down to 3.20.

First step could be to file a bug (or even PR) with CMake, the sooner CMake stops using unintentionally-accepted options, the better the chance Flang can eventually reject that option.

I wonder why they decided to diverge from gfortan-style flags:
