There are internal functions written in Lisp and internal Lisp
variables.  They are frequently not documented too well because it is
frequently hard to document them without explaining a lot of Emacs
internals.  This is perfectly normal.

I don't know if in this specific case the variable is a left-over from
something we don't need anymore; I hope Kim will answer that.  But
your general point -- that Lisp variables should all be documented to
the degree that every Emacs user should understand -- is not valid (as
a generality).
