The "law" that I want TeX to do is this:
- if a word would be printed in the right-hand margin, insert a
  line-break before that word.

That's it.  It's not a NP-hard problem.  It's not violating
conservation of mass and energy.  It's not invoking dice-rolling
for the fundamental particles in the universe.

Sure.  So we're asking if TeX can be tweaked to consider
additional solutions.  (namely, "always add a line-break before
anything with an overfull hbox, regardless of what that makes the
rest of that paragraph look lik")

The answer could be "no, TeX is not flexible enough to do that".
Fair enough; we're accustomed to living within the limitations of
our tools.  But this isn't an "impossible" or "magical" request.
