I get why actual "hot add whilst running" isn't a common feature (VMWare can do it but often does it via various tricks, such as the instance is already 'sized' with the number of CPUs/RAM and some are marked inaccessible).

The thing that really pissed me off is when a cloud provider is UNABLE to add more CPU and RAM on reboot. I even understand having to migrate the instance disks to another host that has CPU/RAM available.

Your frustration with VMs and cloud providers is completely understandable. VMs are essentially entire machines, which makes hardware manipulation quite challenging. However, have you considered using containers instead? They are often easier to manage and offer more flexibility in terms of scaling resources up or down as required. Let me know if you are a developer, as I may have some recommendations to share.
