Oh it's definitely possible. The (dis)incentives tend to be strongly against such secure systems, though.

In the messaging game, there is every incentive to be seen as the secure-est one.

If you can have an e2e chat between two iphones locked in a big glass box with a sign that says "Anyone who can hack into this conversation gets $100M", that's a really good marketing campaign.

If you can make the app use secure enclaves or whatever to take the ~100k people who write the source code of the libraries, app and OS out of the attack surface, that $100M becomes much safer.
