> My initial motivation was wanting to RDP and SSH into my home workstation from a locked-down corporate laptop when I travel. I couldn't install Tailscale on the laptop
I'm not sure it would work but did you try running tailscale client through a docker container so it's not installed directly in your host system?
It would work, but this laptop is so locked down that I can't even install Docker without begging for permission (it's for a consultant role, not a dev role, so...). That said, my stop-gap solution while I worked on Tela was a cheap Linode VM with tailscale installed, and using SSH port-forwarding to get to RDP. Even at that tiny price, it grated me.
