Well, I am increasingly adopting a similar coding practice. A few days 
ago, I also split up archive.module into a small stub which registers the 
menu item and has a page callback, and then that page callback includes 
archive.inc which contains all the magic to display an archive page. This 
does eliminate a great deal of parsing for PHP. Although we use an opcode 
cache here, we observed greatly reduced memory usage if we take care of 
doing our own modules this way. (I don't have hard numbers unfortunately).
