Because these aren't the only file name operations being called. You
have seen it in the backtraces I've shown earlier.

I wanted to introduce `completion-only'. You have said, that it would be
too specific, and I shall use `non-essential' instead.

As I understand the codebase of Emacs 25, no other use of
`non-essential' has appeared since then. Six years later.
