file_put_contents() / file_add_contents() ?

I recall a discussion sometime back about making file_put_contents() (create a file and write the provided contents to it in one command) and file_add_contents() (like put but append rather than overwrite) to complement file_get_contents() but looking in HEAD I don't see either put or add. Was it decided not to create these? Is it simply a matter of noone having gotten around to it? Am I paying too much attention to the voices in my head? -Pollita
