I have a special place in my heart for these sort of "weird" features, which seem really exotic compared to the standard POSIX APIs we're all used to. I just enjoy thinking about alternatives and new ways of doing and architecting things. Even if I can't think of a practical use for such a feature, I always appreciate the novelty. It makes me wonder about the future. Are the typical POSIX-style APIs still going to be dominant 50 or 100 years from now, or will new APIs and ideas start to replace them?

It seems like CPU peripherals are gaining more and more intelligence. I was reading about PCIe's potential successor CXL and the amount of features that allow peripherals to do their own thing with a minimum of CPU intervention seems to be increasing.
So at some point I bet you'll be basically uploading BPF like code to peripherals directly in order to accomplish really fast I/O. Don't know how that's going to look at all from a post-POSIX API perspective.
