I wonder why Apple does not include a hypervisor in iOS, and "risky" processes such as iMessage, Safari (maybe a Secure Safari version) could then be executed in a separate virtual machine. The hardware (CPU + RAM) in the iPhones these days should be able to sustain it. Or would there be serious drawbacks to this ?

I guess degrading battery life is the key here. The battery life is already bad enough and the competition is high to make the battery last longer
