I'm lumping feature requests around SSH fine-grained permissions into a single issue. The first two are somewhat related (around what type of host can connect using a particular target user) and the last one is docs-related.

It would be nice if we could specify the combination of source user groups and source peer groups. A use case here would be I want to allow a user to SSH to a server as a target user from their laptop but not from another production server, if laptops and servers live on separate subnets.
Ephemeral hosts should be a separate peer group and should have a policy associated with them. I found I can SSH as root from the dashboard and want to disallow that.
It wasn’t immediately obvious to me how the previous Access Control Policy and the new fine-grained ones interact with each other. Do I want to specify one or the other? Or specify both as one applies to allowing network traffic and the other applies to target user.

Additional context

From Reddit comment
Authorized keys from format for matching IP address or hostname
