I did look at making this work with the publishing framework. The
problem is that ox-publish looks like it will only do one or more files,
whereas I'm trying to publish a subtree.

More particularly, if there were a way to pass the PUB-DIR argument to
`org-export-output-file-name', that would take care of it. But I can
only export a subtree via the export dispatcher, and the export
dispatcher only calls `org-*-export-to-*' functions, and all of those
functions contain their own call to `org-export-output-file-name', so
there's no clean way to inject PUB-DIR anywhere.

You can't really wait until `org-export-as' does its general keyword
gathering, either, since EXPORT_FILE_NAME and EXPORT_DIRECTORY both need
to be available to `org-export-to-file'. So finding EXPORT_DIRECTORY in
`org-export-output-file-name' seemed like the only option.

I was imagining that EXPORT_FILE_NAME would take precedence, if it was
an absolute filepath. Otherwise, the two options could be complementary.

I don't have this function! org-version -> "9.3.7"
