We have made good progress on object literals as well, although there are still a lot that use the old style, given how ubiquitous object literals are. But the needed reindentation isn't overly intrusive, as changes are limited to the object literals themselves (i.e. they don't affect surrounding code). And given that object literals account for quite a bit of the remaining differences between regular and legacy rules, doing the transition now is still worthwhile.
