Arguments and Attributes descriptions missing in schema of AWS, AZURE, GCP and ORACLE providers

Hello,
I have generated the schema using terraform providers schema -json for the AWS, AZURE, GCP and ORACLE providers. In the schema, I could see that descriptions are missing for arguments and attributes of resources. I have noticed the descriptions of arguments and attributes are available for vsphere provider. So i am expecting to have descriptions for all arguments and attributes in the schema for the above providers. Can i know if this work is in the pipeline?

From the schema of aws_vpc, I have seen that enable_dns_hostnames field has both computed:true and optional:true. And in the documentation also it is mentioned as both argument and attribute. so from the schema how to identify enable_dns_hostnames as both argument and attribute?
