That statement is misleading because it's mixing two things.

You're saying it should be WTF-8 because on Windows, it can be used to hold
improperly-encoded UTF-16 file paths.

And you're saying that because it would be WTF-8 on Windows, it should be
WTF-8 on POSIX systems too.

Both suggestions are fine. I agree with them.

The problem is that the way you wrote, it makes it sound like WTF-8 can be
used to hold invalid file paths on POSIX systems and round-trip those to
UTF-16. That doesn't work. Therefore, any cross-platform content that attempts
to transcode to UTF-16 will have to deal with undecodeable paths any way.
