Not sure, such is the sad state of the world. But it would be especially important to have SOMETHING that can run multiple applications while being 100% sure that it is enforcing security between them. So far everything has been a total disaster, with browsers getting completely owned every year at Pwn2Own, conventional kernels being effectively expected to be locally exploitable at all times (which means all mobile sandboxes are broken as well), and hypervisors where Xen seems to be the most secure of the ones that are mature, and is still terrible.
