I see a problem with the subscribing thing if "mail to subscribers after general edits" is enabled. Subscribers will get a lot of mails though often versions differ only by one character if you beautify your page.
A (maybe cool) workaround may be the following process: If a page content is changed by a general edit a "publish" menu item should be shown near "subscribe". So publishing will be made explicit.
