This already unofficially happens, sometimes for better and sometimes
for worse. Some articles are indeed neglected, but there are many on
which you can't change so much as a bit of wording without attracting
attention.
WikiProjects and setting up "related changes" watchlists are one way
some people try to organize such oversight. It seems to work pretty
well in some areas, and not even just for featured articles---if you add
a new page to any subcategory of [[Category:Mathematics]], you're likely
to get someone stopping by within the next few hours to fiddle with some
part of it or another. (But then we have some very good and diligent
mathematics editors.)
