To my mind the problem is that if you can't use a transliteration standard to prepare a diplomatic transliteration then there is something wrong with that transliteration standard. Surely thats the purpose of a transliteration standard. Note that the rule for normalizing anusvaras to class nasals is a "required rule" and not a recommendation or option. As you pointed out the normalization of nasals is bad practice for transcribing manuscripts. The normalization of nasals was pointed out as a problem in editing manuscripts about 20 years ago on this list:
see http://list.indology.info/pipermail/indology_list.indology.info/1996-February/004161.html
But by making the normalization of nasals a required practice for sanskrit the standard is saying this is good practice.
