Filling at the window's edge is the only reasonable option, IMO.

The behaviour of web browsers was mentioned earlier. But you have the
CSS property max-width to modify that. I have – and frequently use – a
bookmarklet that lets me set the max-width property on the body
element in order to improve readability. It beats adjusting the
browser window itself.

Perhaps emacs could have a variable max-fill-column which, when set,
could govern visual line mode in this way? If set to t, it would mean
use the value of fill-column. Or if set to a number, ignore
fill-column and use the number itself. It shouldn't be allowed to
override fill-column in the other use cases, though. Perhaps
visual-line-max-fill-column would be a better name, if perhaps a bit
unwieldy.
