I only prefer to have its own property because it should be always present and the tags would probably be an array of string with no context

Fair enough. We can always revisit when we add more than 1 encryption. Right now if the switch has encryption turned on it's going to be secio, otherwise it's plaintext. Once tls or quic support is added it will become more important for this.
