No. I'm not even sure why this is a question. The article has instructions on how to use this with macOS, Windows, Linux, iOS, and Android. Both for receiving and sending to each of them. Only two of those OSes are phone OSes.
It's Tailscale SSH, not Tailscale core. Some users don't want SSH key management (or even don't run sshd, especially on Windows) but just want file transfer.
You can already scp over tailscale without running sshd. I'm still not understanding what this provides over scp. Some kind of GUI? Works on phones? The marketing page does a poor job.
How do I scp files to or from my iPhone? Do I have to run some kind of terminal app? Approximately nobody wants to do that. That can't seriously be confusing to you?
While I could probably scp from my windows laptop, id have to do some setup. I don’t really use my laptop for dev stuff. On the other hand, it’s already in my Tailscale network. So I can also just right click a file, and select “send to my-cloud-server”
Same from my iPhone. I can easily send any file to or from any of my devices. It appears in the share menu on my iPhone.
