Please bear in mind that we're not talking about a behemoth like Python or PERL here, with numerous dependencies and files scattered over the system. Lua is a single C library with a simple API, about 50kB in size that can be statically linked if you want. Bindings to other languages of choice are available.

The point is simple: some people suggest to have a simple file format 
with an open spec so anyone can write his own parser. You suggest using 
an existing language and always link to a specific lib parsing it.

I prefer to stick to formats/protocols over libs/implementations. I tend 
to believe a good protocol lives much longer than a good implementation. 
Especially when talking about interchange of data...
