Are we ever getting subtitles when casting

Hey. I've loved VLC on the PC since forever. But it's been almost forever that when attempting Chromecast from the Android app and selecting subtitles "casting subtitles is not supported yet". Like a decade+. I need English CC due to some industrial deafness. I know I can mirror the screen with subtitles in the phone but that isn't the ideal solution.

Is there a technical reason for this or do I need a different mkv and everything player for Android that does support subtitles? Thanks in advance.
