Presumably you mean
S: * 23 FETCH (FLAGS ())
since there is a \Seen flag but no \Unseen flag.
How does the client determine the difference between this and some client
doing
tag STORE 23 -FLAGS (\Seen)
What happens when some other client sets the \Seen flag before this client
got its cache updated?
Are you suggesting that the server keep track of clients, so that it knows
whether or not to present the \Seen flag to that client? If so, how?

Non-sequitor. There was no good reason for the late unlamented 55 MPH
speed limit in the USA. There are excellent reasons for a guarantee that
message data is immutable.

The technical reason is that this tells the client that the message data
is different.
