Apologies for coming into this a bit late.

A couple of points:

1. Hangul canonical composition and decomposition is a separate topic from compositions of latin characters with accents. It is described in 

 http://www.unicode.org/reports/tr15/tr15-18.html#Hangul

among other sources.

2. I think the mount option is a bit of a red-herring. I think we should just do what Mac OS X does - I think in the tech note it says something about storing things always in the decomposed form or composed form. Ideally we should make the differing mount options no-ops. Mac OS X does not need extra mount options, we shouldn't either.
