Docker did do something smart with Docker Desktop by including wsl-vpnkit...to work around brain-dead corporate VPNs that break docker networking. Your alternative solutions don't work when AnyConnect or GlobalProtect, etc, are running.
My suspicion is that since you pay for client connections, they don't want you running a single bastion client and having your real clients connect via that. But it's annoying, and if you really wanted to do that, you only have to edit the script, or set it back on a schedule/after starting up the client.
