I’d be curious just how much cheaper low port count GbE switching would have to get to make reducing the internal connector count and just having both front and rear jacks live at the same time the preferred option. (or whether the unmanaged ones are already cheap enough; but customer requirements around BMC security and VLANs and such would require something nice enough that nobody bothers to make low port count versions of it that would be stupidly expensive in context.)
