I find that quite interesting and it is one of the reasons I've not really considered trying out Headscale myself.
Why? Makes perfect sense to me. Designing a product with a specific use case in mind is good. When you've got the limited resources of am open source volunteer project, trying to solve every problem is a recipe for burnout. If it can even be done.
I mean this is a great advertisement in and of itself. Something being considered "enterprise software" means it will have 90% more features than needed, the code will be a combination of dozens of different mid-level devs new perfect abstractions and will only test code paths through all those features that the original enterprise valued. I.E. it is great if you work in an enterprise as it will generate a lot of work with an easy scapegoat.
