It is not accurate to characterize this as a bug.  Say I have this HTML:

  <form>
   ...
   <input type=text name=One>
   ...
  </form>

If I don't fill in the "One" field, it won't appear in FieldStorage by 
default.  If I create FieldStorage with keep_blank_values=1, then it WILL 
appear, with a blank value.  That's all well-defined and operating as 
specified.

Your bug report refers to a couple of special cases of manual query string 
generation that cannot occur with forms.

But, as you say, this is veering a ways off-topic...
