That’s great, but it should still be possible and well documented for people to run things natively. Some people want less bloat for technical reasons (maintaining a product with very little storage or memory). Tinycore Linux is my go-to example of the benefit of keeping things lightweight for a purpose.
From my experience with tailscale so far - there are so many different ways to have it configured well. If it works well for you having it on the host, then go for it. I have home assistant in a VM with tailscale and tailscale on the (windows) host. This works well for my needs and I don’t mind having it running “twice”
