Thank you for reporting issue.
Version limitation of phpoffice/phpspreadsheet has been removed in 2.1.1.

Thank you for reporting.
Added import and export permissions separate from administer settings permission.

Merged!

> my question is, why not use the 403 - 404 page specified on Basic site settings -> Error pages (/admin/config/system/site-information) when no response body is set ?

Because it is difficult to display content of 403/404 page configured in site settings.
You can use 301/302 and redirect url. This results the same as your code.

Thank you for reporting. Fixed in next release.
