I see.

Is there a policy regarding to changing behavioral of settings in
Org-mode?

In my personal opinion, changing the code to differ between «nil»
and «0» is not that bad. People might enjoy the additional
feature[1] which does not seem to be implemented so far.

Is there going to be another one? In 2009, I did not even use Emacs
and I'd happy to share my settings as well :-)


<just brainstorming>
Wouldn't it be nice to have a tool that scans for my settings,
compares it for changes/mentions in the changelogs and notifies me
upon matches? :-)

[1] Allowing no warning for each timestamp without explizit warning
period *and/or* allowing warning for explizit warning periods within
timestamps.
