The only consequence for not support unpack row length is that you'd have to only use osg::Image that are contiguous. However, this is not an onerous requirement as up until last week osg::Image could only handle contiguous store of image data, and even now all existing image plugins load osg::Image that don't use the now RowLength feature so will all provide contiguous imagery. The use or RowLength is really just a niche feature that a small number of users will use, such as when handling textures that are small portion of large imagery heading in main memory. So disabling the feature would be fine for OpenGL ES, but on setting a non zero RowLength osg::Image under OpenGL ES it should emit a warning that it's not supported.
