genuine question - what’s wrong with storing an encrypted seed phrase in the cloud?

assuming that the key used to encrypt the file is strong (like 20+ characters, mix of character types, and never stored anywhere else)

is it just the risk of creating a weak key for encryption? or is it the fact that a Cloud provider has a wider attack surface (so you are more likely to be a target, even if it’s very difficult to crack your key)? or is it the chance that some encryption method could be compromised some time in the future? 🤔
