Of course, but that pushes the complexity of understanding all this on
the administrator.

I wonder if a better approach here would therefore be a configuration
ability to easily specify intent somehow and somewhere.

Intent being specifying, for typical deployment scenarios, that you're
doing wired/wireless 802.1X or instead something with dial-up /DSL
concentrators.

Different behaviour is optimal in these diverged use case scenarios.
