The hyphenation patterns in luatex are currently saved as strings in the
format file because the internal representation is several thousands of
separate small objects per language and dumping those objects would be
rather messy. We may change the behaviour at some point before version
1.0 is out, but not for texlive 2009.

Besides this technical issue, dumping 50+ languages in the format file
is not recommended for another reason as well: luatex is perfectly
capable of handling patterns at runtime, per language. So it is possible
to load just the language(s) you need for one particular document, and
the speed penalty will be only about one tenth of a second per language.

Best wishes,
