I do not mind. High symbols like "(|)" cross middle line a bit, but 
since it is not TeX and superscript can not be above subscript it should 
not cause any problem with overlapping.

The issue with increased vertical space between vertical bars might be 
alleviated a bit by using e.g. 0.35 instead of 0.5. I hope, subscripts 
and superscripts are still distinguishable.
