The background for this change is here: https://github.com/stamen/modestmaps-js/pull/63 While this definitely is a breaking change and will require a 1.0.0 to release, I think that making this the default, rather than either having two setExtent methods or a magic parameter to setExtent, should be the default. There's a roundZoom() function that can give you the previous behavior.
