Indeed so, completely agree, but given that muscle mass and bone matter loss, together with an ever present increasing risk of cognitive issues will increase at 80+ for most folks there seems to be no point in exacerbating the situation - few seem to completely escape the worst side effects of ADT. Have you looked at the two links to papers/studies I linked/citing the debatable gain of RT + HT/ADT as opposed to RT alone - especially for those over 70/80 and the more so in light of recent improvements/refinements in radiation technology? Worth a look.
