Well, on a second thought, I now change my previous suggestion.
The first process, that is decompostion before applying features, is
not needed and desirable.  In practice we Koreans do not mix syllable
and jamo letters, in spite of Unicode standard.

But it would be better if harfbuzz accepts the third, that is the
composition after features are applied.

Best,
