I agree.

compatibility jamo sequences may be preserved unchanged. Otherwise,
they may be transformed into correct conjoinging jamo sequences before
nameprep based on hangul automata for contructing hangul syllables from jamo
(this will make common nameprep codes include hangul-specific codes in it).
We (KRNIC NC) have no consensus yet on whether these sequences
should be preserved or not.

Hangul compatibility jamo sequences are not rare in korean texts and
are useful for hangul consonant-letter acronyms for long hangul words
or phrases.  They will unburden  typing efforts.
