Am I correct in believing that other browsers choose the display mode based on the DOCTYPE?
I'm not a decision-maker in this group, but heartily against any IE-specific changes in Drupal personally.
IE 6 and 7 have the same display modes as the other browsers (quirks and standards compliance mode) that's triggered by the doctype, it's just that IE8 will introduce a new switch that goes a little further than the current doctype. http://www.alistapart.com/articles/beyonddoctype One potential problem I can see is that someone might create a great module that uses new features introduced into IE9 (a long way away). If Drupal core were to use this new module we would have to include <meta http-equiv="X-UA-Compatible" content="IE=9" /> to take advantage of the module's features. This would essentially lock the rest of Drupal and contrib modules into IE9. Would we simply ignore the module since it requires an IE specific feature (as in excluding 6, 7 and 8)? Or is there a fat chance of this scenario happening at all?
