Ok, so are you saying that from a technical point of view, a typical
browser will simply allow scripts to perform POST requests?

Because it's hard to see how anything but the script can determine
what counts as a user interaction for a specification application.
Mouse gestures, keys, resizing the window, are all examples.

Perhaps.  It seems analogous to popup windows: popups in response to
clicking something are ok.  Popups when you visit a page, leave a
page, or from a timer, are annoying and good browsers block them.

How do we draw a useful line between what counts as a user
interaction, and allowing "web applications" a rich set of interaction
methods which do count as user interactions for this purpose?

If it's to be specified, be careful, as the Firefox folks had a few
learning iterations before they got it about right for popups.
