True, but then, both a small table and a small alist are very fast.
OTOH, hash tables scale better.

It doesn't matter much. I'd still favor a hash-table since it's hard to
predict an upper bound for include keywords in a document, but it's your
call, really. 

I doubt the alist or hash table will be the bottleneck.

You would need to access the alist/hash table for each include keyword,
not necessarily from the same document.

It should be in the scope of `org-export-expand-include-keyword', much
like `file-prefix'. No need for a global variable.
