Retrieving the on-disk location of DRM-free local tracks via MusicKit.MusicLibraryRequest

I am currently experimenting with the MusicKit API, specifically if/how it could replace iTunesLibrary on macOS and MediaPlayer on iOS. My question is specifically about DRM-free tracks that the user has available locally (e.g. purchased, matched or uploaded tracks):

Is there a way to access the on-disk URL of locally available and DRM-free tracks?

In the iTunesLibrary framework on macOS there is ITLibMediaItem.location and on iOS I can get this path via MPMediaItem.assetURL, but MusicKit's Song.url seems to be nil for all of these tracks in my tests.
