Read again, but from the other side of the looking-glass; imagine that you have a bunch of code in E or some other object-capability-safe language, and you want to audit it for Spectre vulnerabilities. As the article makes clear, other concerns are taken care of structurally by E's design; how might E be changed to also help mitigate Spectre?

Capabilities can mitigate exfiltration of spectre'd data exactly as described in the bit I quoted. That's mitigation of, not proof against, but it's something. I'm afraid I don't see your point.
