The reason I mention this is because, sadly, baremetal instance types are only ever the largest size of a given family which is cost prohibitive for most users. And even if cost isn't an issue, they take much much longer to start (like 10-20+ minutes) and they actually fail to start far too frequently. It's really a shame that all instance types other than baremetal have virtualization extensions disabled, otherwise we'd be operating far more workloads in firecracker or kata. We operate huge kubernetes clusters so the cost is roughly the same whether it's fewer big instances or more smaller instances, but those startup times and reliability are terrible for autoscaling.

Please, AWS, bring nested virtualization to all nitro instance types!
