Need multi-page country components in Google Places auto-complete

I need autocomplete in Google Places to give me results from countries: SZ, FR, DE, AT, IT. I know that componentRestrictions can only work with one country. So, is there a way to get results with multiple counties in Google Places auto-complete?

This feature was introduced in version 3.27 of the Maps API in January 2017:

Now you can restrict Autocomplete predictions to just a few countries. You can do this by specifying up to 5 countries in the componentRestrictions field of the AutocompleteOptions object.

Starting with version 3.2.7, you can use an array for componentRestrictions. For instance:

 { country: ["fr","ch","be"] }

However, the number of countries is limited to 5.

Be careful, because if you are limited to "FR", it ignores the French departments. To have cities in all of France, you need:

 'fr', 'gp', 're', 'mq', 'gf', 'nc', 'yt', 'pf'

But since it is more than 5, it is impossible to limit the whole of France.

Google Maps believes the French overseas departments are not in France; this is a big problem.
