If LuaTeX does not open up, there will be a risk of forks. There is already a LuaTeX fork with an
xml parser built in. I can understand the reluctance of the LuaTeX team to include unnecessary
modules, and it would be helpful if there was a "contrib" directory with third party
modules that will be built as a library (.so, .dll) which get installed in the TeXlive system. So
one can say for example 'require "harfbuzz"' and have harfbuzz loaded on all platforms
LuaTeX is running on.
Eh ... luatex is opened up. One can just load libraries. Preloading a
whole lot of (arbitrary) libraries makes no sense. I can imagine that at
some point (when luatex 1 is out) that there will be a bunch of libs
shipped alongside the binary distributions but that then has to be part
of regular tex live and miktex and ... distributions. The thing with
libraries is that they evolve independently and you cannot expect the
luatex team to keep track of them. The only thing we can provide is a
stable api into luatex.
It's not a matter of opening up, but a matter of packaging. Also, when
I run luatex I don't want at some point in the future to find out that
an additional 125 libs (plus dependencies) are needed that I don't use.
A repository with additional modules is a secondary effort, alongside
luatex. I know that Luigi has done lots of tests and is setting up some
procedure for it, but as this is to be supported on *all* relevant
platforms it's not something trivial. So, there will be something, but
not preloaded. (Just like we don't preload macro definitions or fonts or
...).
