Nothing is ever "pure". Linux isn't pure, ultimate Unix philosophy.

ioctl, mmap, sockets could be represented as files, why not?

`echo 1 > /root/some-file/%lock` instead of fcntl(F_SETLK) -- I just made up this syntax

`echo SIGTERM > /proc/15683/signal` instead of kill

Not sure about mmap, since its very purpose it to map a file to memory.

The fact that they're not may be a clue to answering that question.
