Me I really wouldn't like to import a whitelist into something like noscript, you never know what you might be allowing without checking the full list. There are very few sites that I trust, there are more that I have allowed to run scripts because for the site to function they effectively have to be allowed either temporarily or permanently, but trust is something that has to be won and not just given because of some whitelist .
Since adblock plus works opposite to noscript it is easier to build a blacklist as there are many sources for that in one form or another, but a whitelist is considerably harder because you are allowing it to run scripts, not just block ads.
So a worst case scenario you don't see some legitimate content, that is taken as an ad, to allowing a site to run malicious code. So for the well known they too would be personal preference again and wouldn't take long to manually allow them, so if it's a small number it is hardly worthwhile bothering, I just know I wouldn't trust a whitelist that has the capability to run malicious script if any entries are wrong.
