I am curious since the default value of `LIBCXX_INSTALL_MODULES` is false. Then it looks like we need to teach someone else (the packagers?) to enable that explicitly.

The feature is still considered experimental and typically we don't enable experimental features by default. I don't see modules stable in LLVM-18.

If vendors want to ship it they have to enable it. They also need to adjust their packaging to ship the new files. I'm not sure whether Debian will put it in the `libc++` dev package or a new experimental package.
