I'm happy to report that Jenkins works fine with PowerShell 7!
I have this in my connection log:

The Agent is connected, disconnect it before to try to connect it again.
The An illegal reflective access operation has occurred is probably
something something Java 11, and I always ignore such warnings.
Maybe someone should consider reporting this to the maintainers of
org.jenkinsci.plugins.envinject.service.EnvInjectMasterEnvVarsSetter? :-)
This is how I configured the node with Ansible:
- name: Install Win32-OpenSSH service
win_chocolatey:
name: openssh
package_params: /SSHServerFeature
state: present
ignore_errors: yes
- name: Install Powershell Core
win_chocolatey:
name: powershell-core
state: present
- name: Set the default SSH shell to PowerShell
win_regedit:
path: HKLM:\SOFTWARE\OpenSSH
name: DefaultShell
data: C:\Program Files\PowerShell\7\pwsh.exe
The ignore_errors: yes with openssh is because I use the same Ansible
playbook for Packer (which goes to AWS) and Vagrant (which is for testing
on my local machine), and the local VM already has SSH running and I
haven't bothered yet with debugging that, so I just ignore the error when
Chcoclatey can't install OpenSSH due to port 22 already in use.
But anyway: for anyone not using Ansible: you need to set the registry key
HKLM:\SOFTWARE\OpenSSH to the full path of pwsh.exe.
Powershell legacy and Powershell Core have a different executable name,
intentionally, so they can be used side-by-side.
I hope this is useful for anyone.
