"Are there any other voting methods besides IRV, meeting the
'later no harm' criterion?"

Yes. 

FPP, Woodall's  Descending Solid Coalitions  and MinMax (Pairwise Opposition)
all meet it.

DSC fails Mutual Dominant Third and Later-no-Help.

MMPO fails Plurality, Majority for Solid Coalitions and Mutual Dominant Third and
Clone-Winner.
