Rather than kerning, think of it as the regulation of spacing in the 
line, much like one adjusts the widths of the spaces for justification 
in western typography. This is way beyond the ability of the fonts. For 
example, one needs to regulate the aki/space around ruby, tcy, warichu. 
Doing the work in the font would mean that fonts would have to know 
about all those objects.

There is also the consideration that all those controls need to be 
placed primarily in the hands of the document designer, not in the hands 
of the font designer. At best, a font designer could provide an opinion 
about *some* aspects. For example, in western typography, the font 
designer could give some guidance on good min/max width of spaces. In 
the case of Japanese typography, the tradition is to use values that are 
not font-dependent.
