I would imagine they are stuck back a few decades when delivering documents on paper was standard and nothing unusual. So printed paper is a minimal acceptable format. Since part of the legal battle is to also drain the other side's resources it would make sense then to go by the absolute allowed minimum and nothing more. If delivering documents on posted notes was allowed surely they'd be companies specializing in that.
