 As noted by @pbiron in comment number 66:

 The above (Note: see [48688]) commit did not include the requisite changes
 to `WP_MS_Themes_List_Table`.  The impact is that in multisite, the
 `Enable/Disable auto-updates` links will still appear for externally
 hosted themes on the `Network Admin > Themes` screen.

 I'm looking into what it will take to add the multisite support for this.
 It's complicated by the fact that plugins use an array (returned by
 `get_plugin_data()`) and thus can use `array_merge()` on the info in the
 transient, `array( 'update-supported => true )` and the plugin_data;
 whereas themes use an instance of `WP_Theme`...making the array merge not
 possible.

 I think something can be worked out using the magic `__get()` and
 `__set()` methods of `WP_Theme`...but still looking into that.
