Thanks for pointing out the omission. The information is now on the
webpage and will later appear in the code itself. I've opted for the
same license as LÖVE: the zlib/libpng license

That is a very good question. I've been waiting for it :-)
Apart from the retort "why not in the table?", there are two reasons.
1. It is easier for the user to access and change them.
2. Subtables inherit via the `__index` metamethod.
Both are not insuperable: access methods can be provided, and there is
no reason why metatables can't have metatables themselves. If someone
can answer "why not?" cogently enough (e.g. by just going and doing
it), I'll consider that.
