It does look like they support SAML and OIDC. I think the idea here is that many (most?) Tailscale users will be corporations, and most corporations would rather integrate Tailscale access with their existing auth system, and not have an extra employee account to deal with that needs to be disabled when the employee leaves the company.
That does make things harder for small shops where things are more ad-hoc, or an individual hobbyist who wants to use it. But not sure how much of Tailscale's market consists of people like that, or if Tailscale even cares that much about that segment. No judgment if they don't; that's a perfectly reasonable decision to make.
