The "To Do" list is more a list of things that *could* be done than a
list of what is actually happening. If something is causing problems for
you now, then yes, you should file a bug, because then I know that it's
causing a problem for someone, and because then I get reminded of it
more often. (I look at the list of all libsoup bugs in bugzilla a lot
more often than I look at the ToDo list.)
