Although you can't browse it, you can instruct Evernote to keep a local copy of all your data, allowing you to keep incremental backups. You can find (and change, if you want) the database folder under Tools/Options, General.
I do agree with your other points, although there are significant limitations to using the filesystem for storage in an application like Evernote. Perhaps a good compromise would be to use a publicly available database engine like postgres (although I'm sure they derive advantages from their proprietary format beyond the mere fact that it's proprietary).
