Technically they both require having OneDrive with settings that allow the option "Specific People"

If they don't then get an error, but otherwise are there other reasons why this is not available?

They require OneDrive within the resource tenant, not to mention the number of compliance-related issues being able to do this would cause.

This is not true, when you share a file in your OneDrive with "Specific People" they don't need any specific tenant resource access. They get an email with the link and can access the file.

@mikkele @Vasil Michev I think it should be added to the conversation that when you use sharing links with a federated user they are being added as guests in the resource tenant because that's whats making the federated user able to access the file, not being a federated user anymore.
