All other messengers have this functionality for years. This is minimum

Really?  I never noticed any indication that my emails had been read
before I got RCS.

"email" is not "messenger". Don't get confused with that - these are to
fundamental different services.

E-Mail uses long existing standard protocols like SMTP, POP3, IMAP and
can be used with clients like K9 mail, Google Mail and so on. It is also
a federated infrastrucutre, which means you can have a GMail account but
you can also send e-mails to people at Hotmail or any other custom
domain which has e-mail services enabled - because servers of the
providers accept messages from other providers outside their own
network. Yes, this has some limitations to avoid spam, but this is the
general idea of federation.

Messengers on the other hand are mostly proprietary non-federated
services like WhatsApp, Signal, Telegram, Threema etc. which use servers
of the respective provider (like Meta in the case of WhatsApp) and they
send messages using these servers. You also can not send message from
WhatsApp to Signal or Threema. If you have friends using Threema you
either also need a Threema account or you have to convince your friends
to join the messenger service you use yourself.
