I think there probably do exist quite a lot of individual customized
systems to connect Org planning files to associated source code files,
and this is definitely a viable use pattern.
But I think a simpler more direct approach is possible - simply an
outline-minor-mode on steroids (=> org-minor-mode). If I structure my
source file with headlines like an org file, do visibility-cycling,
structure editing etc. like in Org-mode - why not add TODO's and
priorities and tags and properties to my headlines? The functionality to
do that is already there in Org-mode, and the syntax-elements used would
be exactly the same. Except the comment-syntax involved ...
