I've been thinking about this and it doesn't really make sense...
Why do (server) motherboards have 10G RJ45 Ports? 10G RJ45 is power hungry, not well established and has comparably high requirements on the cable.
it would be much better if the 10G RJ45 ports were replaced with 10G SFP+ ports. You could then easily use the onboard networking with existing infrastructure (10G SFP+ switches or 40G switches with breakout cables), save a lot of power and reuse existing SFP+ cables.
SFP+ gives you much more flexibility, because even consumers could decide to use fiber, which is often much easier to hide in home scenarios.
And with SFP+, you still have the option to go with RJ45 if you absolutely need to, by just buying a couple of 10G RJ45 transceivers.
I think every consumer who uses 10G RJ45 nowadays can safely be considered a power user and most of them would probably prefer SFP+ instead of 10G RJ45 because it gives you much more flexibility
It can't reallly be a cost thing, because the Network IC, e.g. Intel X550, works with both 10G RJ45 and SFP+.
The only issue is space on the board, but the existing motherboards with SFP+ ports like the ASUS Z11PA-U12/10G-2S clearly show that it is possible.
