Linguistic precision notwithstanding, my recommendation would be to
defer to convention here. Of course, I also defer to the maintainer. :)

According to the docstrings for org-agenda-todo-ignore-deadlines and
org-agenda-todo-ignore-scheduled, the definition of "past" includes
today:

,----
| past    Don't show entries scheduled today or in the past.
| past    Don't show entries with a deadline timestamp for today or in the past.
`----

I suppose my chief question is whether it would be possible to preserve
the current behavior of "past", while introducing a new setting to
accommodate the functionality you seek (e.g., "old" or, better yet,
integers)?

Indeed, it is relatively easy to change the settings with a search and
replace. Somewhat harder is catching all such changes in the release
notes. ;)

My concern has to do with the precedent this sets. I would submit that
incompatibilities be introduced only with the utmost caution and in
cases of clear need. If I remember correctly, obsoleted settings and
variables are usually gracefully deprecated (e.g., org-agenda-span vs.
org-agenda-ndays). If each release contains multiple small breakages
because individual users would like to change conventional naming, it
can become difficult to keep up with org-development. Of course, such
decisions are in the hands of the Bastien and Carsten.

What do you think of the possibility of using positive and negative
integers (e.g., -1 for past only, 1 for future only, -7 for anything a
week or more in the past, 14 for anything two weeks or more in the
future, and so on)? Would that perhaps be a way to add some
comprehensive logic and fine-grained control to this setting? I'd be
happy to work up a patch to that effect.

Thanks for taking the time to respond to my questions!

Best,
Matt
