There's always a risk when updating any extension, including the vital Core extension. And yes, it sucks that AEP Tags doesn't allow you to rollback to a previous extension version if an error is found.
You could choose to ignore the updated extension. But if you ignore the extension versions repeatedly, you run the risk of losing out on new features or even bug fixes.
Personally, I update extensions regularly. Then, I also test my rules to ensure that nothing has been broken unexpectedly.
