Writing another 3.x patch would also help other people and might be more 
'fun'.  That is the situation I am in with respect to Idle.

Like Steven, I would be interested in specifics, though I do not 
disbelieve you.  I do not believe those two attitudes are exactly 
official policy, and I may request more discussion of them on pydev.

I know.  Some core developers are trying to revamp the issue-patch 
handling process to remove some of the busywork, use our time more 
efficiency, and make it work more smoothly for everyone.

But let me try again.  I am discussing a situation where a core 
developer has either requested or already agreed to apply a 2.7 
backport.  I have seen such in the past, but maybe this is now rare.

I specifically would like to be able to request backports for Idle 
patches and get responses.  When requested, I really would apply 
responses that worked.  Really.

But I now realized that most people would rather write a patch, on their 
own schedule, for an issue that bugs them, and perhaps use it locally, 
even if rejected for the repository, than write a guaranteed patch 
'right now for a issue of no interest to them (and which might require 
python knowledge they do not have).

Yes.  All changes on as issue, including uploads, are emailed to all on 
the nosy list regardless of open/closed/... status.  However, I would 
inquire first.  "If I backport the committed bugfix to 2.7, would you 
apply it?"
