It sounds like if I'm splitting and rejoining precomposed syllables
myself, this change isn't necessary for me; my rules would split a
sequence like <L, LV> into <L, L, V>, then later recombine it into <LL, V>
or <LLV>, regardless of whether it originated in the text or was created
by the shaper.  So as far as I'm concerned it should be left to the
HarfBuzz developers to decide whether they want this change for other
reasons unrelated to my project - and I imagine they will decide they
don't, but that's up to them.
