Additionally, aws_eks_node_group is missing support for setting suspended_processes as a parameter to the ASG it creates.

Support for price and capacity optimized for allocation strategy is a must for us:

Not going to happen on provider side until AWS EKS API actually supports this. You can check for available options at https://docs.aws.amazon.com/eks/latest/APIReference/API_CreateNodegroup.html

Everyone commenting in this issue need to bring this to their AWS TAMs.

@z0rc so I guess the only way for now is to do it via the aws_autoscaling_group...

these are all dependent on the upstream service - once EKS managed node groups support these configurations, the provider can therefore support them (most likely via custom launch templates unless the EKS API dictates differently)
