If you still want to know the answer to something to a valid question (eg not a bug) and can maintain the question (keep up with comments), there's no reason to close the question.

In my opinion this isn't a bug report, it's asking for a way to disable xrandr from doing something, and you're perfectly active with it so it's fine.

In terms of going forward:

 - A rewrite would be advisable. Make it less about the bug and more about what you're trying to achieve.
 - Involve the people that suggested it in the first place. Ask them to post an answer if they know how (even if it's "can't be done")
 - Bounties are a good motivator for tough questions.
