Our goal is to provide solid, common interfaces for Linux users to rely
on. Not give way to vendor specific "solutions" like uploading ini files
to perform device configuration.

To be clear - I'm suggesting the creation of a more targeted APIs 
to control the settings you have encoded _inside_ the ini file. 
Not a new interface for an whole sale config upload.

Worst case scenario - if the settings are really device specific 
you can try to use devlink device parameters.
