I own a 12" Macbook as a secondary machine and frequently bring it with me to travel. I have never felt the need for a second USB-C connector.
What would a second USB-C connector do for you?
It cannot support 4k @ 60hz. I know this because I also own a Dell 27" 4k display to pair with my main machine. I have only connected the Macbook to the display via HDMI (by means of said adapter). It supports 30hz at best.
I have not tried a 1440p display. It (of course) runs at 1080p just fine.
They do appear to have caved to the demand for irrelevant nonfunctional details like chassis colors.
OP's request is arguably far more important (read: functional) than rose gold tint.
It's like meeting a beggar asking you for spare change and one asking to come live with you; "caving" to the former doesn't really cost you anything.
