I agree! Just to be clear, by "security critical" I mean the tier where you'd also refuse shared VMs. I'm not convinced most people have workloads and threat models that actually need the isolation they say they want, nor a fully considered notion of what their preferred primitive buys them (per your footnote, and any number of other issues I'm completely unaware of). But I like and appreciate Workers, and am grateful to be paying less because Cloudflare bin-packed more.
