I thought about it when I was, again, cleaning up "External links" section in number of articles after IPs adding bunch of unnecessary links, which was adverts of their sites. We (sysops) have "block page" feature. Maybe you can do a feature that will be blocking one section from editing (just like whole page: no restrictions, only registered, only sysops). It will be useful, because then I could work on some articles instead of clearing all spam links...
The spam links would just be added to another section. Or another page. Get the spam sites blacklisted at [[m:Spam blacklist]] if they're persistent. More generally, I can't see a lot of benefit in protecting one section when anyone could edit any of the rest of the page.
Changing all WONTFIX high priority bugs to lowest priority (no mail should be generated since I turned it off for this.)
