It was intentional, cf b16259b3c and the linked discussion.

+1, although I wonder if we shouldn't follow pgindent's new lead
and require some argument(s).

The POSIX spec for find(1) gives an example of applying find to
what they evidently intend to be a plain file:

    if [ -n "$(find file1 -prune -newer file2)" ]; then
        printf %s\\n "file1 is newer than file2"
    fi

So while I don't see it written in so many words, I think you
can assume it's portable.
