You're assuming that feature matters to me (it does but I have a lot of users relative to servers, so even the most basic tier of userify express or their cloud offering would handle my needs for dramatically less than premium tailscale). What you're missing is the foundation of being able to deploy something like this depends on easy acls that integrate with my current identity system (i.e. saml) because I need to be able to control access per business unit so that when the mesh of everything is brought online users still only have access to the subset of systems they should have access to. This matters whether it's Sheila in accounting who only ever uses it to remote desktop to her on prem workstation, or jackie in IT using it to manage on prem servers across multiple locations and cloud servers. So yes, maybe a small subset of my users are actually using enough of the premium bundle to justify that cost but I can't even mix and match because the basis of every use case (the ACLs) are only in the premium package in a functional way.
