That's hard to port in my book. It makes code more clumsy, and I could
understand when a project would not want to import related changes.
The problem is also that you often don't even see those problems - like
the various problems in coreutils "rm" that were caused by this.

Yeah, that would be sane and fine for us, too :-)

So does anyone have any more suggestions?

Besides mentioning BeOS and Haiku, I cannot do much more. Haiku is not
an important part of the industry, there is no way to deny that.
