When I run Media library import
then I see Media entity already exists. Not creating a new queue item for "file.jpg"
and only new images are added as Media (77 in my case)
but all the existing files are duplicated in Files (all 6716 in my case)
Successive media imports add the files again (my counter stopped at 10000)
Don't add files to Files unless the files are associated with new Media
---
Is this a bug? Is there a way to prevent files from being added to the files list (files_managed) that I'm just not aware of?

I tried to replicate the issue / use case you report and I cannot reproduce, with 2.1.1 release.
Files listed in the (Drupal 10 default) Files View (/admin/content/files) are not duplicated, in case the Media Image (using that File) is always in the website.
Files get duplicated only when Media Images are removed / cancelled before a new import ...
and that is a Files View issue, that doesn't properly remove Files previously imported and then un-used ...
