Yes. Let's sort out what means "received", "displayed" and "read" to
decide which of them are needed and which are not.
Yes.
So:
What's the use case for needing to know when the user's client has
received the message?
If sender wants to be sure, that client on the other side received and
processed the message. So, the sender is sure that once the user on the
other side will pay attention to its client application, he'll be able
to read the message.
If delivery of all the previous messages were confirmed by the <received
/> reply and THIS one was not, the sender may assume, that the message
was lost somehow and may try to resend it (if he wants).
This helps knowing which messages are lost in cases of brutal
disconnection, decrypt failure, ...
