I think you're right on #1, that if you create a VM via API you can add
multiple nics to the same network so long as you're not using a VPC. I
don't know for sure off the top of my head though

We could give some basic examples, but it's largely going to come down to
specific OS, for example with linux, it could change by distribution based
on the udev rules, the config file locations, dhcp client differences, etc.
It would be up to the admin of the VM guest to know how to set up a network
card on their guest OS.

Worst case is that the OS doesn't recognize the new NIC without a reboot.
So either you make them power the VM off always before adding a NIC, or let
them try to add the NIC and they can reboot if the OS doesn't support it.

No, I think there is a team who specializes in this. I was thinking the
other day that the UI will likely always lag behind the API in features,
because new features won't get time to be implemented in UI on each release.
