You may rather need to hack on `org-export-get-environment', possibly
extending it. For example, we may allow more flexible
`org-export-options-alist'.

Note that you can simply use `buffer-local-boundp'.

Attached is a concept which might be useful. At least it detects when
variables are set locally and then doesn't attempt anything.
