The UA that I'm working on does do paragraph-at-a-time line breaking,
and already tries to avoid having a short last line.  For body text,
perhaps that's already enough, without having a property to control it.

(If there were a property to control the choice for body text, then I
 don't think that having a fixed "any length up to k is completely fine,
 and any length greater than k is completely unacceptable" control is the
 right way to go: having a short last line does have an aesthetic cost,
 but any shuffling of words to correct it will also have an aesthetic
 cost, sometimes greater than the cost of a short line.  E.g. for a
 justified body paragraph with only two lines, having a short last line
 is often the best available choice of line break.  So I think that any
 control property would need a more refined way of drawing the line
 between what corrections are worthwhile and what corrections aren't.)

I do agree that headings are a bit different, though: for a heading that
takes up two lines, it can look a bit strange even if the second line has
quite a decent length, like three words occupying a third of a line.

So something like a last-line-length:50% declaration might be useful for
headings (so long as it doesn't result in any other lines having a length
less than 50%, at least).

Another possible approach for headings: does CSS have anything that would
have the effect of making lines have roughly equal length?  That might be
useful for pull-quotes, or for use with text-align-last:justify.
