While we've mandated that "__" must be used for semi-public functions, we've
never said that it can't be used for private ones. One could argue that the
use of "__" for even private functions avoids a required rename if the
function is made semi-public, and adds information. For example, I know
that most of the functions you list above are FS-related and probably
logically related. But I wouldn't suggest a universal policy change at this
