End point of Asubha practice

Asubha practice is certainly found in the sutra-anga of SN/SA. However, the practice is not included in the notion of ‘right view’ in terms of the so-called seeing-knowing ‘things as they really are’:

Also, all the nine progressive stages of meditation (i.e. the 4 rūpas, 4 arūpas, and the cessation of perception-and-feeling ‘saññā-vedayita-nirodha’) are the results of mental projection (saṅkhārā). Only the ‘cessation of desire-hatred-delusion’ is based on true insight of the real world (i.e. ‘right view’):

So, asubha practice is not the core teachings of SN/SA.
