File Metadata should be editable also when translation doesn't exist yet
In the backend form of sys_file_reference inline records, typically there's a link where you can edit the metadata of the selected file.
Since the fix for #82178 this link is removed if there is not sys_file_metadata record in the same language as sys_file_reference record.
However obviously editors want to edit metdata for files which have not been explicitly localized before. So I suggest that sys_file_metadata translations are created on demand in this situation.

In our project we're using this patch so that metadata translations are created on demand: https://gist.github.com/smichaelsen/f5d425b84db7007a512eff0a26247939
