A long shot, however we can all provide feedback to Apple…
Here is the link to Apple product feedback, you can select Apple Music service.
What I submitted to Apple is below.
Subject: Roon Integration
Feedback Type: Software/Hardware Compatibility
Comments:
Access to Apple music is only available through Apple applications, which limits my ability to access through other music curation and playback solutions and interfaces.
What Apple Music feature is your feedback about ?: New
Comments:
I currently use Roon (https://roonlabs.com) to manage, curate and playback my music collection. This solution provides a single interface and reliable high-bitrate connectivity to all of my high-end playback devices, regardless of their manufacturer.
Roon includes seamless integration with Tidal (https://tidal.com) and Qobuz (https://qobuz.com), allowing me to see streaming offerings and favorites alongside my own music collection.
The feature request is that Apple support these types of integrations widely used by HiFi enthusiasts.
