The font designer should chose those parameters based on how they
intend their font to be used. Since TeX is fairly sophisticated with
its stretch and shrink, however, a fixed proportion of the width of a
space character (which has also been designed along with the font)
will give good results most of the time.

:) I agree. It's much better to teach users how to deal with bad
boxes (\begin{sloppypar}, etc.). A mechanism to warn of underfull
boxes in a paragraph would be nice, though.
