Both of these call ucs-normalize-region, which makes it natural to save match data in that function. Conversely, anything that calls ucs-normalize-region would have to be wrapped, not just the two functions you mentioned. In other words, there seems to be no advantage in saving the match data in those functions, only disadvantages.
