i think this is a case of "if you build it, they will come".   there 
really isn't a migration path from traditional latex math to unicode 
math, hence a completely new method is required like \omathchar.    
people will migrate to the new method if/when they see a benefit, 
especially since it can be made backward compatible for the most part.  
since we all believe 16-bit math/symbols would be beneficial, it will 
happen.  if no-one steps off the edge of the cliff and puts out a 
proposal, then we'll all just wallow around wondering why things aren't 
progressing.
to my limited viewpoint, \omathchar seems a reasonable starting point, 
and you'd have some leverage with two schemes using it.
