I'm not sure.
I'm a professional tinkerer and I run Debian stable. OK ok it's not an immutable distro but my point is that I do tinker, just NOT with my main OS.
I'll tinker in containers, in VMs, in my ~/bin etc but NOT in what hosts all that.
So I would argue that what's important for tinkerers is to establish clear boundaries on what they want to tinker on and what they do NOT want to tinker on, what can change vs what should never.
