I'd probably say no. They added the export events feature so they don't have to do this. For stuff before that was added (like your info field stuff) in the past they only did that if you gave a smallish time span for them to search (ie Y10.001 to Y10.012). However usually doing that takes a long time for pages to load and has been known to crash/seriously slow down the game for everyone else.
Unless the archives have been changed recently I doubt the admins would look into them for something as insigificant as an infofield change.
