IIRC, because it contained these strange beasts which functioned as both files and directories - i.e. cat would return data, but then you could cd into them and run ls. Linus (among others) didn’t want to permit those violations of the file-directory dichotomy into the Linux kernel.

Oh that's funny- I remember a much much earlier Linus mentioning how this would he possible in Linux, I didn't know anyone actually did it.

I think you really should be able to "cd" into any kind of structured data.
