>Simple things are broken: Ableton couldn't even trigger a microphone permission prompt, forcing me to meddle with a SQLite database, which is definitely not meant for end users to touch, just to get it working.

You shouldn't have to do any of that. Even if Live couldn't trigger the permission prompt, you should be able to give it a microphone permission in Settings.

For whatever reason, apps need to request the microphone permission first to show up in the settings menu. For other permissions you can drag/drop the application into the settings window, but not for the microphone permission.
