Because any mathematical alphanumberic character can appear superscripted  
in mathematics; does that mean that we need to create superscripted characters 
for all of them? If these are part of a small, closed set, like U+02B0, then  
it's appropriate to encode them; but if just any character can appear  
superscripted or subscripted, then it goes outside Unicode, and needs to be 
dealt with in markup.
