With Tailscale at least, you can pretty easily share a node with someone else. If your target audience are solo developers or hobbyists, making it even easier to share access is surely nice; from the perspective of someone in charge of making sure our company IT is balancing security and ease of networking, the literal last thing I want is making it easier to grant someone access.

There are policies defining who can talk to what; they are deployed from a GitHub repository with defined rules on who can modify them and who has to review them; there are zero scenarios where I want an alternative way of granting access to any device or service under our control.
