Takeout is "fine" for core services (Gmail, Calendar, Contacts) but unusable for anything involving activities and events. Examples:
- Google Maps search history, custom maps, stars
- Google Photos albums, comments, activity
- Google Search activity
- YouTube stuff, of any kind (unless you use something like Soundiiz, but even then it's nothing like Google Play Music was where your files were YOUR FILES, and somethings aren't available on the streaming platforms)
