I'll publish feeds when I get around to making a UNIQUE feed script. Running another copy of alt's or xeroc's scripts adds no extra security (negative security due to false perceived security?) but makes me feel "done" with that task.
Can't we argue that some scripts can be compared to other scripts as objectively better? So stakeholders shouldn't want a poor script just because it is unique. I am sure there will be scripts that cannot be objectively compared because of some value judgement, but in that case we have a choice of having diversity in the value judgements made by these scripts or to just choose the scripts that make value judgements that is agreeable to most stakeholders (or perhaps proportional representation would be better?).
What I am trying to say is if we had one open source script that was really great (as in it would be hard to argue that any other script is better than this one) which takes the price of many different exchanges into account in a sensible way (factors in volume as well as a weight of the credibility of the exchange, which itself would somehow have to be communicated by the stakeholders to the delegates who actually set the weights in their scripts), what would be the issue if all 101 delegates use that one script? Is it a concern of putting all eggs in one basket in which a vulnerability found in the script could be exploited by whales manipulating the market in clever ways (I can't imagine the scripts are that complicated that we wouldn't quickly find nearly all of these vulnerability if we had many eyes looking at it). Or are you arguing for security through obscurity?
I think even if all 101 delegates were runnning that single uber script we would still have better security than if only 86 are running multiple scripts. For example, if 49 delegates were to collude to run a different script to, for example, profit from unfair margin calls, they would be able to seriously manipulate the median price in the BitUSD market right now. But if all 101 delegates were providing feeds (even if was through the same script), then that attack by the 49 colluding delegates would not be possible.
All of this isn't to say that I want the reduced stakeholder pressure from you providing feeds through alt or xeroc's script to prevent you from making your own awesome script.
