Hello!
And we would do well to refuse doing such thing. Foundation would become a huge bottleneck and community will then begin complaining that we are hindering the development of the projects.
Well understood and appreciated.
Yesterday I tried to do one tiny tiny change (es.wikipedia wanted to switch their timezone). Of course, after last flames it was fun to make a circus out of it (forced few people - sysops and bureaucrats to 'sign in blood'), but here again, accurately interpreting votes and resolutions in other languages, where there were multiple votes on same page, as well as Great Walls of Text, was nearly impossible.
Lots of things can be rolled forward and backwards, so usually no harm is done - except that it takes time and can cause some frustrations, if caught in the middle of heated debate.
So, we usually have just to trust that people who come and ask for things can really represent community, and are not going to undermine something in evil ways. Usually we like to trust, and love to trust. But sometimes a single campaign against can shatter it all.
