That's what I don't understand. The comment is explaining which <LV,T> combinations compose at the character level. I think you will find that LV combinations only exist for <Modern,Modern> combinations. It is at that level that <Old,Old,Modern> is excluded. What you seem to be after is a change to the text on line 1154 from "Only the <L,V> sequences for the 11xx ranges combine." to "Only the <L,V> sequences for parts of the 11xx ranges combine." or "Only the <L,V> sequences for some L and some V combine." The interesting bit of Unicode history is why the consortium caved in to Korean demands for the full set of <modern, modern, modern> to be included. An uninteresting bit of HarfBuzz archaeology would be whether someone briefly thought that the all L and V in the Hangul Jamo block composed at the character level.
