It may or may not be correct.
For example, when exporting to Org (ox-org), one may want to keep the
environment variables.

If we add this feature for export, it should be an export option.
It will also be a breaking change.

I generally feel that it should be reasonable to go ahead with this
breaking change, possibly disabling variable resolution for ox-org only.
